Okay, so I can't figure this one out. It seems whenever I open the windows explorer to look at files, explorer.exe starts eating memory, increasing by well over 100MB per second, until it has consumed nearly all of my 4GB of RAM, and my computer freezes. I've tried killing the process w/task manager, doesn't work. same with process tree. I'd love to take a screenshot to show this, but the memory locks up too quickly to be able to PS+C+P+Save. It seems to happen most often with the folder i use to save music I've recorded (my own instruments, not from the internets lol) but has occurred a few times otherwise. I haven't installed anything new, or odd, so can't quite figure out how its happened. I've got AVG Pro, doesn't find bollocks all!
