Since I have my menu bar full, the My Center button appears to the side clear. When I attempted to click it, it started to glitch (Sorry for bad explanation of what happened, its hard to explain without video). When it glitched, it acted as if the button was not there and would sorta shake up and down a bit.. As if the website were having a seizure or some weird spasm.
Screenshots of what my center looks like. --> http://prntscr.com/2i0m31
Now in the screenshot, it only shows you what the button looks like. When you actually try to click it is when the bug happens.
I will come back here with any further issues I discover.
* EDIT * I noticed it actually only occurs when your mouse is not over the main menu bar. Otherwise it is ok.
