I have been using the trial version of Caedium Professional with various imported STEP geometry items to examine the software's suitability for my requirements.

The method of highlighting then selecting geometry (faces, edges etc) using the techniques demonstrated in the screencasts (holding down the right mouse button and moving the cursor over the geometry etc) do not work properly or reliably. This also applies to the technique using the select tool and left mouse button.

After a fresh restart of the program I am able to highlight 2 to 3 geometry features using the above techniques until this functionality stops working. (This functionality may return sporadically without predictability.) From then on I am then forced to open the select dialogue box and manually search through all the faces, edges etc to select the geometry I require. This becomes extremely tedious with larger geometry with 100+ features, particularly as the screencasts demonstrate that geometry selection should be able to be done with ease.

This is the only disappointing feature I have encountered with an otherwise very good software package. Unfortunately for me, it's a show-stopper.

Are there any know issues (64bit, Windows 7, STEP geometry etc) that could cause this problem?

Thanks.
