Continued crashing

[WHirsch]

Is this crashing problem specific to a single file, or to Chief Architect? If so, I'd try a clean installation after giving the registry a good flush.

Ver 10 is very stable, though I have seen occasional crashes when intensively editing cad. There may be a corrupt block or other object in the file. Try working with other files to see if you can reproduce the crashes. Hardware problems are usually a longshot, but a bad mainboard, or bad/mismatched ram can cause overall system instability.
