If I monitor select/deselect events within a tab using Dialog.WatchTab and I add Windows Quick Access to the tab watch list, after navigating to Quick Access, which only contains pinned links, a never ending sequence of select events is triggered whether or not anything is actually selected or deselected. I am guessing that Windows is doing something unusual under the covers for what is a non-standard folder.
As I work around I will modify my code to avoid watching Quick Access.
