Though jv16 wrote the bug would be fixed in the next version, the "list processing bug" is NOT fixed in Registry Cleaner.
After scanning the tool listed 256 entries in the results window (raw list).
I had to click several times (3 X) repeatingly the "remove" button to get removed all selected items in Registry Cleaner.
In other words: I selected all the items in the list, clicked on "remove" and then the cleaner removed a number of entries and then stopped. I had to repeat the action three times to get all listed items removed.
