When deleting mail in OE I get this message:

"An unknown error has occurred. System does not support the specified encoding."
Hotmail Server: http://services.msn.com/svcs/hotmail/httpmail.asp.

I can clear messages only if I attempt to delete them from Inbox, then click on a different folder, then go back to Inbox.

Anybody had this problem?

I'm using Windows XP Home SP2 with all updates.
