i activated active window tracking (i.e., mouseover sets focus to a window) via tweakxp 4, didn't like it, turned it off in tweak, but the system continued to function as if it were on. after turning it on, reboot, off, rebooting i uninstalled tweak - system still acting as if active window tracking were on. did some googling, found the appropriate registry entries (current_user>control panel>mouse>active window tracking) - changed this to 0 reboot, no good. turned to 1, reboot - no good, turned back to 0, reboot - no good. deleted the registry key - no good. system restored to back a week, reboot - no good. did all the above again after the restore - no good. undid restore, did it all again - no good. using several different registry tools i found and removed every registry entry dealing with tweak - no good.
5 minutes ago i bought a paid membership to ee for just this problem. it's only allowing me to assign 500 points to this question but if there's a way i can do more, i'd be more than happy to.
