@pendean, Here are my responses to your questions:
1. I work with AutoCAD 9 hours a day, five days a week. Commercial Architectural Millwork - Woodworking.
The "No selection" thing seems to be a once a day thing; sometimes twice, sometimes not for a few days.
Seems to be no trigger - I'll be working along, and then stuff quits working. Happened in the middle of a Block Edit session yesterday.
2. The issue usually is happening across all open files - 2-3-4 open at a time. Even continues if I open a new blank file. Can draw stuff, select it, mirror it (I think), delete it, but cannot modify it in any way via grips or Properties.
The yesterday, I closed all open files except the one in which the problem started, and that file was OK when I came back to it. I could continue with the block edit. I did, however, save and quit just to be safe.
3. No, I do not reset AutoCAD every day. Volker suggested I reset in one of his e-mails, so I did. I had to bring back my acad.pgp, and acad.pat files, as well as my three personal Tool Palettes.
4. I have a second screen with Properties & Tool Palettes (three tabs, for blocks, and hatches) floating/open/visible. Layers, Xref, and Insert Block, and Design Center floating/rolled up. I yesterday decided to stop using the Block and ADC ones.
Another thing Volker suggested is that it might be a Network issue. Here at work we are on a One Drive / Sharepoint system, and all files are stored elsewhere, by year and job folders. Speed has not been an issue, unless I am trying to work in my work PC from home. Then I will copy the file local and upload when done for the day.
The No selection issue happens on my PC at home also, when working in a One Drive "Documents" folder.
Today I will copy drawings to the top of my C drive, and see if anything different happens.
NO ONE else in my office (3-4 on acad) has reported either the "No selection" issue or the "copy" command hard crash.
Good Morning, BTW, and thanks for the reply.
