Fixed a bug calculating caster with an upper A-arm and a lower "virtual" A-arm.
Thanks to Gavin for this one.

Fixed a bug in the Delphi IDE that caused some dialogs to not open correctly.

Fixed a bug in the trailing arm with lateral links geometry calculation.
Thanks to Riku for this one.

Corrected a compiler bug with Excel2Input and Excel2CMM.
Thanks to Maurizio for this one.

Corrected a bug in eCalc and vCalc.

Corrected the terminology in Dynamic Results from 'Roll couple distribution' to 'Roll stiffness distribution'.
Thanks to Jason for both of these.

Updated About to identify Windows 11.

Calculations are always carried out in sequence. Even when initiated from the menu bar, each of the dependent calculations will be calculated in sequence. If any calculation fails, the appropriate error message will be shown. That error will need to be corrected.
For example, if Rates is to be calculated, and an error message indicates a problem with the Roll & Bump calculation, then Roll & Bump will need to be corrected and calculate error free before the calculation sequence can continue.
Occasionally a calculation may not complete and appear to hang. Previously the only way to terminate the calculation was to use the Windows Task Manager.
All calculations are now performed in a dedicated CPU thread with a timeout. If a calculation has not completed within this period, then it will be terminated and an error message shown. This is a fatal condition and SusProg3D will be terminated. To avoid losing any data changes either do a Save before doing the calculation, or tick the Save data file when calculating setting option.

Extended the caster calculation limit from 0.5R to 0.8R (28.6 degrees to 45.8 degrees).
This particularly helps with semi-trailing arm rear suspensions with large amounts of bump and droop.
