Although we're still using Adobe Reader 9.1 here, (no real problems except that it's slow opening), many find Foxit Reader smaller and less resource hungry.. It's your choice but here's the link:
Hope this helps.
I am using Adobe Acrobat Pro 9 with a Core2-Duo computer running WinXP and 1GB of memory. The computer runs fine. However, Acrobat crashes repeatedly. It appears to happen for any reason: trying to copy highlighted text, clicking buttons on the toolbar, scrolling fast through a document, etc.
I have tried two "home remedies": (1) a 45-minute Repair Adobe Installation (under Help), and (2) checking to see if I had any "acr.dll" files in my Windows/Temp file. No acr files were found (my Win/Temp folder was completely empty). This last was from an "Excessive Acr.tmp File Creation" post elsewhere in this forum and the Internet.
The Adobe users forum <www.forums.adobe.com> has nothing specifically about my crashing problem but it does have a lot of other seemingly basic problems mentioned by some upset people. My Google searches indicated to me that Acrobat 9 is a problem-rid program.
What do you think is the current wisdom about Adobe Acrobat - can it be fixed or time to jump ship?
