Mike Yeah, I see your pain. The thing is, there is not much I can do in this case. This behavior is not part of my code, this is either UI framewrk or even Windows itself. Not somthing you can easily change. Actually there is another task in backlog - adding another form for quick assigmnent of tags and albums, something analogous to F2 for assigning people. I think once that will be released, this problem will not bother you anymore since you will stop using context menus for assigning tags.
However, right not it is not first priority so I can’t actually tell when this will be relased.
