I was hoping someone had an idea on how to get rid of the scrollbar in the start menu while using a framed start menu. If I use a uniformly colored start menu, this would not be an issue, but I wanted to learn at least some image editing and I thought that a frame for the start menu would be a good starting point while getting a hang of how margins work at the same time.

In the second image, the second value of ContentMargins is set to "-10" and this gets rid of the scrollbar but at the same time it messes up my frame. I've fiddled with almost every property/value pertaining to this but I can't get it to work. Some help would be much appreciated!
