Have you tried all of these things?
Uff...I have a hunch that the problem may related to tool palettes acessing blocks from that drawing. Any chance that is the problem? I've also spent time deleting tool pallettes related to the dwg, deleting them from my content browser, and then re-creating them...but still having trouble. everytime I close the drawing, I get the same error message.
