Jenny,
Try to set the SDI system variable to 0, in lieu of 1. This should gray
out the "single drawing compadibility" box under "options>system".
In essence, you're doing the same thing by unchecking/checking the
box.....but it works for me.
Command: SDI
Enter new value for SDI <1>: 0

Thanks for the suggestion. I'll just have to live with it. I am not running
any project wide utilities when this happens. I'm glad it's happening to
someone else too. I thought i was just going crazy for a while
