1.

Small sliding bug fix when rock slides on the first segment of the rock slope.

1.

Improved CRSP import.

2.

Added documentation for how to duplicate CRSP results.

3.

Can now choose to display Imperial US energy units in ft-lbs.

4.

If three vertices were collinear, and a barrier was on the second vertex, the rock paths were incorrectly calculated.

5.

When Slope roughness was used, the modified slope angle was not being used for the calculation of exit velocities in the x and y direction. The actual slope angle was being used. The modified slope angle is now used for both entrance and exit velocity calculations.

6.

Can now plot height above slope when plotting bounce height through collectors and barriers. Use the right-click option to subtract slope height from Y elevation.

7.

New Help System.

1.

Under rare circumstances the clipboard would be corrupted. Fixed.

2.

Excel charting of multiple datasets would sometimes not work with Excel 2007.

3.

Security system update to allow for educational updates and improve commercial network version.

1.

Rocks sliding along horizontal slope segments could pass under a barrier. Fixed..

1.

Fixed datatips not showing on Windows XP system. Bug was introduced in version 4.046.

2.

Added "DATATIPS ON", "DATATIPS OFF" indicator to status bar. Clicking on it toggles datatips state.

3.

Reading in files from DXF with a large number of vertices would give different results then when the file was entered manually. This due to near colinear points not being treated properly when reading the DXF file.

1.

Fixed a bug which altered the energy of a rock incorrectly after it slid into a barrier and exceeded the barrier’s capacity.

2.

Changed the drawing code so that rock paths aren’t updated every time a rock is thrown, only after ALL rocks are thrown, greatly increasing computation time.

1.

Fixed a bug which caused the program to crash if the user hit File...Close after reading in a file.

2.

Fixed a bug which caused barriers and data collectors to move incorrectly when std. deviation was applied to the slope.

1.

Converted help system from winhelp to webhelp to be compatible with Windows Vista.

2.

Re-organized start menu folders and links.

3.

If a linear portion of a slope was divided into smaller segments by adding extra vertices, rocks which were in sliding mode would slow down at each vertex, even if the line segments had the same material properties. This has been fixed so that rocks in sliding mode do not lose velocity when crossing a vertex of co-linear line segments with the same properties.

4.

Adding barriers or data collectors no longer affects the pseudo-random results.

5.

Updated technical support dialog.

6.

Improved User Interface look under Windows XP and Vista.

7.

Toolbars no longer split into two rows.

1.

Fixed a bug which caused rocks to register multiple hits on barriers instead of sliding down them. This caused errors in the data charts.

1.

Barriers did not use the capacity with sliding rocks (they had infinite capacity). This bug was introduced in version 4.043. Fixed.

1.

Fixed a bug which caused the program to time-out when a sliding rock with downslope velocity intercepted but did not break a barrier.

2.

Improved printing code. On certain printers (or with certain outdated printer drivers), the program would crash when trying to print.

1.

Now supports multiple HASPHL locks on the same USB hub.

1.

Fixed a bug where a slow moving rock could pass under a barrier and be recorded improperly on a data collector.

2.

Menu checkmarks would sometimes not be rendered correctly.

1.

New Hasp-HL hardlock support. Removed support for old beige hardlocks.

1.

Support for new Educational system. Also update dll's to latest microsoft versions.

1.

Additional Documentation "Determining Input Parameters for a RocFall Analysis" tutorial is now installed with RocFall. It is available in the program (RocFall->Slope->Material Editor->Tutorial) or (RocFall->Help->Manuals->Determining Input Parameters), and from the Windows Start menu.

1.

In certain cases, rocks that were sliding uphill AND off the end of a segment, would cause problems. (e.g. if a rock bounced off a barrier, and traveled up slope). This is fixed. (rocks sliding downhill were not effected).

1.

Improved import of CRSP files that have many adjacent cells with the same properties.

2.

Improved printing

3.

Hardlock and Nodelock software upgrade.

4.

Exit velocity of the rock was not calculated correctly when rocks broke through barriers. The error only effects rocks after they have broken through barriers.

1.

Improved performance for beige hardlocks.

2.

Update to auto-update code and nodelock code.

3.

Bug fix for network version and path path dialog.

1.

EMF/WMF image files now export correctly.

2.

Improved license management for network versions.

3.

Improved look under WinXP.

4.

Bounce Height Envelope did not always load correctly, after a file was saved, and re-loaded. This is fixed.

1.

Data Tips were inadvertently turned off with no way of turning them on. This has been fixed.

1.

Printer logic has been changed. Printers are now set up just before printing. This isolates a problem with printing to some HP printers due to a HP driver bug.

1.

Automatic update technology added. Customers with a web connection will automatically be notified and allowed to update when a new minor version is released.

2.

A new splash screen.

3.

Nodelocking now possible.

1.

Printing without print-preview could cause the slope to be offset to the side of the page.

2.

Large standard deviations could cause negative values for the mass of the rock. There is now a check to prevent this from happening.

3.

Double-click on seeders and barriers to edit their properties.

4.

Barrier Editor dialog now has cancel.

1.

Some version 3 files would not open if they contained rock paths.

2.

Added an Invert Filter option to the Rocks menu. The option sets unfiltered paths to be filtered and filtered paths to be unfiltered. This is useful for locating paths that did NOT impact a barrier.
