Internet Explorer "Standard Buttons", "Address Bar", "Links" greyed out

Internet Explorer "Standard Buttons",

"Address Bar", "Links" greyed out!

I ran into this problem a little while ago.... absolutely annoying. Here is the problem. I believe it started when I tried to install the google toolbar without uninstalling the yahoo toolbar. Needless to say not exactly a good idea.

Here is the fix that worked for me... use regedit (for windows machines) go to:
HKEY_CURRENT_USER\Software\Microsoft\WindowsCurrentVersion\Policies\Explorer

Change: NoBandCustomize = 0

This solved the problem for me.
I hope it helps you too!
