Missing menu bar AutoCad 2005

[Ralph2]

When I last opened a drawing the "only" items on my menu bar were Acrobat Markups and Adobe PDF... I managed to get the items back by searching from F1 finding "menuload" and re selecting all the available choices.

I am curious as to what brought this on. This drawing had previously been opened in AutoCad 2006, is there a connection? Any other possible reasons... and how to avoid them..

Thanks for any insight
Ralph

Same thing happened again this morning. This is getting really annoying. At least AutoCad 2006 is no longer suspect..I don't suspect the following messages have anything to do with the problem??

swfileconv.arx is incompatible with this version of AutoCAD.
