We have a customer running Outlook 2007 SP2 on a XP Pro SP3 PC.
Outlook works fine, except if he right clicks on a document, chooses "send to mail recipient" and brings up a new email with that as an attachment.
Once this window is up it keeps the focus of Outlook.
So you can't maximise outloook, you can't maximise any other other window that may be minimised.
The only window you can open or do anything with is is new email created by the "send to mail recipient" action.
I do remember something like this before that was resolved by tinkering with the graphics card settings - but I may be wrong!
Many thanks in advance for your help,
