I have been using CCleaner for over 3 years now, run it before I close-down my computer at night. Recently, just over 2 months now, when I activate the cleaner by clicking on the icon I have on my desktop it takes so long for the analyze button to change to black from the grey it is when I open it. The programme opens immediately but the analyze button is greyed-out, it takes 30 seconds or more to change to black so I can begin the process of cleaning. Anyone know why it is doing this thing?
