I have 4 users who are having a problem opening their Notes mailbox. When they try to open the mailbox with a double click the workstation hangs. However, I can open their mailbox from my workstation (using the double click) and if I try and open my mailbox from their workstation the system hangs. The weird part is that if I use the GO TO command, I am able to open the mailbox. All 4 users are on different servers and the problem occurred on the same morning. I have tried reloading the Notes Client, using a new DESKTOP.DSK file, a new CACHE.DSK file. I even ran the offending system through a up-to-date virus checker. And finally, the Notes KnowledgeBase noted possible problems with Video Drivers or Sound Board conflicts. No conflicts on these pc's. I would love to run FIXUP against the mailbox, but unfortunately I don't have access to the server. HELP, this problem is driving me CRAZY!
