Just started having this problem with my Dell Dimension 4100 desktop - I can not open or generate new any emails from my MS Outlook 2000. When I double click or try new, it just goes into stall. Preview works fine so I can read them. I have uninstalled and reinstalled Outlook with no effect. When I send emails from my ACT 4.0 program, it works fine. I can also read emails from ACT. I also have same setup on a laptop and when I log into my email account, it works just fine. OS is Win 98.
