Widows tray

Am having this problem with my tray. I am using Win 8.1, I.E.11. The problem is that ,often, when I have to click on a program. I need to get to the bottom to click so to as to isnstall., etc. The tray is set to hidden , yet often will not minimize and freezes, I often have to minimize the program to be able to click. Very annoying. Any ideas? Thanks.
