For electrical schematics, I have a block named Contact. If I use the Insert command, as soon as I type "Con" (or "con" or "CON"), an error message apprears:
An unexpected error occurred. The application became unstable.
It is recommended to save your work to a temporary file and restart the application.
If I type "tact" and then fill in the "Con" the insert block operation completes without error. Selecting the block from the drop-down list works fine.
Anyone else see this behavior?
