I am using Microstation V7 and I was trying to mirror a rev cloud that I created and I got this error message. "Access Violation occurred at 0x60affca1" press OK to continue, Cancel to Exit. I pressed OK and the drawing was frozen, so I used task manager to get out then rebooted program. Went back into program to continue my work, trying to move a triangle closer to the revision cloud. The triangle wouldn't move, you saw a shadow of the triangle but it disappeared. I couldn't delete it or explode it, nothing could be done to it. So again got out of drawing and rebooted it and went back into the drawing and same thing. Could not do anything to the triangle.
If anyone has any ideas please contact me!
