The way to get the Hotbar graphics out is to try to locate the place in the Registry and delete the entry
Most basic and direct way is to Press Start >Run>type regedit in this box press OK
Then when the window opens click on Edit(top of screen) then press Find from the menu then press F3 to find the Next occurrence repeat until you get a "finished searching" notice
Now in this box type Hotbar and report back how many time it comes up?
Do NOT attempt to delete yet

if you do it in the wrong place you can cause real trouble The only
safe place to delete is under the sections marked:
HKEY_CURRENT_USER\Software
HKEY_LOCAL_MACHINE\SOFTWARE
These are the main front doors
Anywhere else is Dangerous ground

Leave alone!
