Sorry for the cryptic title. For the past few weeks, for some reason, when I click on the upper right Minimize or Exit icons, the response is not what it should be. With Minimize, the Outlook window disappears but Outlook does NOT show up in the taskbar. When I open Taskmanager, Outlook is there.

When I click on the Exit icon, I do not get asked if wish to empty the deletion folder and when I open Taskmanager, Outlook is still running!

If I exit by going to File/Exit, then a popup asks me to delete or cancel the deletions and Outllok actually exits and disappears from Taskmanager.

I have not detected similar behavior in any other applications I've used in the past few weeks.

I am running XP Pro, SP3.
