A few weeks ago I upgraded 8 users from Acrobat 8 or 9 Pro to 10 Pro and one, the most thorough user of the product (of course), is constantly having this problem. While she's editing files, both secure and nonsecure, areas of the screen will disappear and the outlines of error messages can be seen; sometimes text is visible: "an internal error has occurred." Using Enter or Esc goes through multiple identical messages until they're all closed, at which time Acrobat still has black or blank sections and can't be used, but can be closed properly.
I have uninstalled Acrobat and Reader and reinstalled just Acrobat, but nothing has changed. I've also flushed the user's Windows profile. I've seen bad RAM cause problems in one application and no others, but it tested okay in this instance. Any ideas?
WinXP SP3, 2GB RAM, Intel(R) Core(TM)2 Duo CPU E4400 @ 2.00GHz (2 cores)
Thanks in advance,
Jon
