[IR Ss2/Ss10] DTM Files Created in Ss2 Now Crash Ss2 and Ss10 If I try to Edit Feature Properties

As part of our migration to Ss10, we are recommending our users write all corridors to individual DTM's and all Corridor Components to 3D DGN Files. Is some instances, it might be necessary to modify a features properties if they need to be displayed in Ss10 due to changes to our XIN files.

I have tried to modify multiple Feature Properties in the Feature Properties dialog box, something that I have done many times in the past. In both versions (Ss2 and Ss10) when I select more than one Feature at a time in the dialog box, there is a delay and then, the session closes without any error messages or anything. One minute I'm in Power InRoads and the next, I'm staring at my desktop.

Does anyone have any suggestions? BTW, I'm in ProjectWise.
