At work my IT department has forced deployment of McAfee Host Intrusion Protection System. It seems to cause conflicts for WindowBlinds. Probably no real surprise there.

It causes strange errors in applications, such as Outlook not being able to start up, issues with changing WindowBlinds themes, etc.
I added the wbload.exe to the permitted application list within HIPS and put a per application setting on Outlook.exe to not be skinned in WindowBlinds. All to no avail.
I am posting this on the very slight chance someone else has HIPS installed, and has figured out how to get WindowBlinds to work.
