Upper right hand button problem

Thanks, Yuri..I installed WinSnap. Hopefully, tomorrow, I'll try to learn how to use it. In the meantime, I found out why that virtual folder is acting that way. When I click on the arrow, the folder opens and shows the icons (large) for the apps within. That flyout ends up both above and below the cursor - so that one of the icons is below the cursor. Consequently, TLB thinks I want to open that app. So, the app opens and the flyout disappears - almost instantaneously. Don't know if that can be corrected in the future.

Also, the problem with the To Do List went away after rebooting.

Thanks......
