I found out why my Autosave was taking 3-5 minutes by looking in my temp folder and finding the ACAD temp file (.ac$) was 253MB.
How can this be resolved?
My only thought is the number of x-ref's. It's a stair section file so of course we have 6-8 x-refs that also have 1-2 x-refs in them for a total of 17 or so x-refs in the file. However in acad 2005 this was never a problem.
Maybe it's something else, i have never seen this before so i am up for any suggestions.
