Solved: I uninstalled CCleaner and switched to another app!!!! As painstaking as it was re-creating my 390 custom wipe folders/files in the new app, in the end it was worth it to no longer have that annoying popup! Congratulations, Piriform! You lost a once-happy customer because of your annoying programming for license renewal notification!
The popup notification appears and stays there and covers parts of apps I am using and it is extremely annoying that it keeps on happening. It's one thing if the popups started within a week or two of the license expiring, but my license expires in 3 months and I don't want to have to put up with this annoyance for 3 months!!! How can this be stopped? If it can't, then there should be an option for "don't remind me again." Thanks.
