very surprised it should be so complicated.
No joy with the killTT programme. Got an install window, checked the box that says "run now" and then..... nothing.

The other options you've given me don't lead me very far either. I found HKEY_USERS in regedit (all by myself! ) but I don't have a "control panel" file in default, so now I'm stumped.
in default, i've got "predetermined" and "dispfilename" and that's all.
