Something's gone nuts with my dynamic blocks. When I try to pick the grip for a lookup list, Acad repeats the last command, just like I had hit the enter command. They had been working fine. I've restarted Autocad. I've rebooted my computer and opened another unrelated file (so I know it's not the file). No change. Everything else in Acad seem to be fine. What's going on? (I'm using 2006)
