strange...it works fine here on Firefox and IE10.
I guess try the site in IE10.
If your a big fan of the Start menu though, then this one is it because it is the real Microsoft Start Menu...I guess MS left behind the Start Menu in the Windows code and this guy has re-enabled it, and I guess anything short of major changes to windows(a new Windows version) would be required to remove it, since jump lists and various other functions rely on it, removing it completely would cause them serious compatibility issues. MS just hide the native win 7 start menu, and this one brings it back in all its glory.
If you get the site to work, I hope you give it a shot because if you liked the windows 7 Start Menu, then your already at home with this...because its the real deal MS start menu, just re-enabled
