Visual studio 2005 toolbox icons messed up.

When I started VS 2005 today I noticed all my icons where messed up :

This makes finding the right control a little harder.

The solution is quite simple : Right click the toolbox and choose reset toolbox,
and presto , icons back.  Unfortunatly this also removes any custom items and tabs in the toolbox.

I also read that deleting all tlb files in  C:\Documents and Settings\_username_\Local Settings\Application Data\Microsoft\VisualStudio\8.0 can work, but did not try it myself.
I don't know what other things might be removed when you delete these files, so be carefull!
