>On occaision, while browsing a table and pressing page down, I get the error "Error reading file." and the browse window closes. If I go to another machine I don't always get the message. Can someone tell me why this is happening? I think it may be related to cache but can't be certain. The tables do not seem to be corrupted.

Is your table located on the local machine? I have seen this on machines that have trouble maintaining a network connection. Otherwise I would suspect you may be having some problem with your harddrive or other piece of hardware. Good luck.
