After Microsoft Office Outlook 2007 is running for a long time, Outlook 2007 stops updating the screen correctly. For example, you may experience any of the symptoms described underneath:
Parts of the Outlook window are now blank.
Parts of the Outlook window are now transparent.
Views are draw incorrectly or incompletely.
Icons may disappear.
Toolbars may disappear.
This issue occurs because a leak occurs in Graphics Device Interface (GDI) objects when you run a VBS script or add-in application in Outlook that accesses an Outlook.mailItem.GetInspector.WordEditor Property. The number of GDI objects increase without being released correctly.
To resolve this problem, apply the following hotfix package
