Maybe, but there are many times that I will be running for some time and quit everything and still show that over 600MB is being used. It is not letting go at will. That or more likely, I have some .apps with some serious memory leak issues. I think Java 1.4.1 is a culprit, but I'm not sure how to check. I'd be nice to have a RAM First Aid that acted like Disk First Aid that just compressed all the RAM that the sys needed at the moment and let everything else go completely.
