Hi bamapete, sorry but you must have "Run Ccleaner when the Computer starts uncheck", and also found out by accident that the best way to have the Compatibility View Settings feature is with all of them checked, it will log you out as soon as you surf away from websites that are not compatible with IE8, found the problem about ten minutes ago. Got rid of the problem by doing what I mentioned above.
Let me make it very clear, that I "do not" in any way, shape or form blame CCleaner with the cookies problem we are having, I love the software and had it for a few years. But it is true that as soon as I downloaded IE8, the cookies problem began, and I do believe that the browser is the one causing the minor problem, but I also love IE5,6,7,8 etc.., I am hooked with Ccleaner and IE* for life.
