I've just downloaded the 30 day evaluation. Many of the screens have text chopped off. For example, the Registry Cleaner window visually has two "sections," though there is no visual separation. The lower section, containing the description of the Selected Setting, overlays the upper section, covering the last line of text. Similar overlays exist on many windows. My resolution is 1920x1200. Changing to a lower resolution does not change the display behavior. Can this be fixed? In some cases there is meaningful text that I can't see.

I bet you are using Large Fonts with your Windows, you can adjust this from your Display Settings. In order for PowerTools to display all the texts correctly, you should use the normal font size.
