The latest build (3.2.0.1354) has several new bugs in the Registry Cleaner:
1. On scanning, the progress values freeze if the scroll bar is used to look at the different scan categories to see which have finished. Scanning continues, as the arrows change to checkmarks. It may recovers in some time (10-30 seconds, depending on number of errors found), and then the progress shows normally and scrolling also works. (Settings: defaults = normal engine setting, History data unchecked, Active X unchecked)
2. When scanning is complete, if you select all, the first category (Invalid file or directory reference) is not checked. Selecting none check only this category. Selecting highighted checks all categories, even though nothing was highlighted. Opening any category removes the check from it and all entries if it was checked, and the inverse if it was not.
3. One way or another, getting round this to check all entries and all categories and then clicking FIX (which should fix all) leaves one category unchecked and unfixed if categories are not opened, or if all were open and everything checked, then it leaves one item.
4. Trying again to fix this remaining item fails; it just unchecks. However, if you uncheck it, you can then fix it as this reset the checkmark.
5. I've never seen this behavior before. Using Windows Pro x64, Dell Optiplex 9010.
