After a quick search, I did not find a current post on this.
AutoCAD 2022 - after running a script where I set FILEDIA=0, did my thing, and set FILEDIA=1, the dialog box does not show up. Checking FILEDIA at the command line shows = 1.
Hitting the ' ~ ' at command prompt does not bring up the box either. Has anyone else had this happen? The only way to get the dialog box back is to quit AutoCAD and re-open.
