I had went back to ccleaner 2.18 as 2.19 kept doing something to thunderbird, where everytime thunderbird starts, the message pane would reappear on thunderbird. Deleting localstore.rdf in thunderbird profile worked, but right when running ccleaner 3.19 again, the message pane is back.
Guys, ccleaner is {messing} up applications, which ain't good.
I had my thunderbird profile backed up numerous, if it wasn't I'd be one pisssed off person.
Better fix this, and I bet real soon, this thread is gonna pile up with the same problem. Give it a week.
Stop ccleaner from corrupting localstore.rdf in thunderbird.
