This happened a few years ago. I run custom clean and as soon a I minimize to system tray, CCleaner closes. I need a definitive answer as the product no longer functions as promised.
ccleaner is no longer running reliably without constant attention. I do not have any boxes that say to show ccleaner in the system tray. Clicking the minimize button closes ccleaner.
ccleaner closes when minimized to system tray. I tried uninstalling and then re-installing but it still does the same thing. This is new behavior. It used to stay pinned to the system tray at all times.
