Hmm... I wonder why your VM use is so high, mine is 37MB here on a 64bit hosts that's been running for a month, with a few hundred windows (tho it's nothing to worry about: the VM use is generally due to dynamically-linked libraries and doesn't necessarily reflect any use of *real* memory). FWIW, my RSS is 4MB, which is about the same as yours. By today's measure, ctwm is very lightweight (tho it's not the reason why I use it). Stefan
