A clarification to my earlier messages about Registry Cleaner Fix not working. Fix works when I use the Fix button at the bottom right of the screen. However, if I right-click on an entry or group of entries (after selecting their check boxes) and select Fix, the context menu Fix does not work. I apologize for the earlier confusion, but I rarely, if ever, use the Fix button - I always use the right-click context menu Fix.
Also, in Settings-Maintenance, when I click on any button, such as Delete temp files, the program freezes, the window starts flickering, and CPU usage spikes to 100%. I have to shut the program down using Task Manager.
