win2K: can't create toolbar or view quicklaunch

HI All,

I had to re-install win2k and in the frenzy of installing, updating and tweaking noticed that:

1. right click on taskbars is inoperative
2. cannot create new toolbars
3. quicklaunch panel is gone (not micro-microminized, gone)
--> the shortcuts are still present in
%/Applications/Microsoft/IExplorer
4. view files as thumbnails does not exist.

I've gone back to the tweaking programs and tried to reset everything to default but don't know if I caught everything. Can anyone suggest a fix?

Thanks
