Hi gabranth,this may? be a flaw in the new N360 version.I have a brand new pc with 4GB ram and yesterday had a pop up tell me that Firefox was using a high cpu usage.Surely this can't be right so I ignored it (for now).Be patient and they will work this out and others with much better knowledge will be along to help.I just wanted to let you know that I'm getting similar messages.
