Corner Menus Glitch

I don't know what it is about my computer but Windows 8 completely hangs up whenever I try and point my mouse in any of the corner menus. It will freeze for around 30 seconds and then nothing happens. Not sure what's going on here but everything else works flawlessly. Spec wise I'm running a custom desktop; Intel i7 processor, GeForce 570, and 8G of RAM. Wonder if people are having similar issues.
