But if 4.6.9 works to solve the problem why would not one step up, to PM 5, also work to solve the problem?
Here is an attached example of what keeps happening. Along with the lag this happens often - when I go from one image to another it often freezes like this and looks like there are no more images after the one I'm looking at when there are hundreds more. It holds here for about 20-30 seconds before the photograph resolves and I can move onwards.
I've got two other computers and have been running PM for years and never had this problem. I'm stumped.
