(Re)assigning hotkeys

Hi,

After creating my own startmenu (and killing the startbutton with Startkiller), I've tried to reassign the Winkey to opening the startmenu. This hotkey doesn't work as expected, the original startmenu is still opened.

Also, I wanted to assig the Win+R hotkey to the openrun program in my startmenu. However, when doing so Win+R doesn't seem to be working anymore! ??? No Run dialog is opened ???

Is it possible to overrule the default Windows logo hotkeys without using a thirdparty tool?
