Outlook 2003 Quick Close Problem

[John]

Hi,

I use Win XP and recently installed MS Outlook 2003.

If I enter Outlook directly (i.e., from the Window's XP main screen)
everything works fine.

If, however, I first go to my ISP and home page, then click on the toolbar
"mail" button, a funny thing happens: Outlook opens just long enough for me
to see the screen, then it immediately closes.

I assume I have a setting incorrectly set, but I'm not sure where to look to
fix this one. Does anyone have some insight on fixing this one?

Thanks,
John Wood
