CCleaner v5.44.6575 64 bit free version
Since upgrading to v.44.6575 CCleaner does not clean on startup, even though that option is selected in Options/Settings. The CCleaner icon in the taskbar says "CCleaner (Cleaning...)" but does not show a percentage like previous versions. When opened CCleaner is not cleaning, so the taskbar icon never reverts to "CCleaner monitoring is active" after cleaning.
When reverting to v.5.43.6522 it behaves as it should - cleaning on startup, correct taskbar icon messages.
