to my main situation, it seems like everyone had varying degrees of success or issues than my issues. Basically I was asking if anyone had similar issues (not necessarily with my file). I have a 64-bit operating system and Windows 7. Another user has a 64-bit operating system and Vista, and has similar issues, but not nearly as bad as mine. I am thinking it is the combination of 64-bit Windows 7 and AutoCAD. I have eliminated Adobe Acrobat as the issue because it works well with other programs on my system.
