Caroline, That is strange that you have 512 MB and still have that kind of problem with gradual deterioration of computer performance especially while switching programs back and forth. And I take it that both machines you refer to have Windows XP or Windows 2000? These would have the least memory leakage of any of the operating systems. Perhaps someone on the board here can give you some idea of services you might turn off on those machines to help you free up some resources which might alleviate or even solve the problem. Good luck, Bill -- To post a message to the list, send it to jfw@xxxxxxxxxxxxx To unsubscribe from this mailing list, send a message to jfw-request@xxxxxxxxxxxxx with the word unsubscribe in the subject line.
