On an x64 Windows 7 Desktop PT Version 2.0.0.966
I'm not sure if this particular repeatable bug has been reported above. I can make it happen at will.
1. In the History Cleaner results, double-click a line referencing only files (for example, Macromedia||Flash Player).
2. You get two AVs in a row when continuing the application, then the normal List Data window for files appears.
3. The AVs do not happen when you double-click a line referencing only registry entries.
4. I don't know what would happen for a line referencing both (none on my system now, AFAIK).
