Thanks RejZoR and DavidR. I changed my settings as you suggested, and it appears to be working now. From what you said, I take it that IE must handle cache files differently, so that setting isn’t needed when using IE. But it is needed when using Firefox. Is there any reason not to keep that setting when using IE? I have not used Firefox enough yet to know for sure if I can abandon IE altogether. Thanks much for your help.
