I've just upgraded to 4.2.6 and although it is working fine the one problem i have with it is that it is trying to use all my CPU power. It is running at the moment at 90% and my usage is always at 100% now. I gone through the options limiting upload and download speeds but it doesn't seem to have any affect. How can i get it back to normal so to speak. My last version ran at about 10% !
