Since I downloaded the latest set of patches, moving between Outlook folders is extremely slow, sometimes taking over 10 seconds. I checked Task Manager and there was nothing obvious. I run Vista and Outlook 2007 on a Dell Latitude D830 with 2 GB of RAM. I know the memory is a bit skimpy, but when I switch folders, the disk light is not even on, so I don't think it's a memory issue. My anti-virus is Symantec.
