When I have all the restricted sites enabled in SB Windows Mail is very slow in some areas, like previewing messages. Without any restrictions everything is fine. There was an update from MS that might have started all of this. It's KB931768. Not really sure about this however. I found out about the restrictions on one of the MS newsgroups. Seems that Spybot also creates the same restricted entry. Anyone have any idea on what entry is causing WM to behave like it is?
