FYI:
If you are using SpyBot ver. 1.4 and sometimes a "garbled" Registry Change window pops up.
Window has "overlaps" and "blank boxes" and offers no options to accept/reject registry change.
Until SpyBot is "fixed", there is a work-around.
Whenever this "Registry Change" window appears, the "change" can be accepted by hitting the "A" key or you can deny with the "D" key.
This is not very pretty, BUT it works [most of the time] and gets you out of a "dead-end" without having to use "X delete" to remove window.
