Yes TweakUI used to have that option, at least version for Windows 98. I certainly can not find that option in this latest version for Windows XP... that is also caused by the fact that in Windows XP, even if those programs are incorrectly uninstalled (partically deleted from the hard drive and not using proper uninstall procedure), once you try to uninstall them from within Add/Remove console, it will report that it's unable to proceed with uninstallation.... but... but, it should offer an option to REMOVE that entry from the Add/Remove list... and it will do that without any problems.
At least that's how it works on my system.
Also, I'm telling this 'cause I remember that Tanya mentioned that she uses Windows XP.
Cheers !
