I have been running Memory Stick since the Mac OS X 10.2.5 update and like on many machines it was showing that as my day progressed, the "unused" (yellow) coloured RAM was growing until it took up about 2/3 of my available RAM. When I upgraded to 10.2.6, which I understood repaired RAM leaks, the same behaviour was detected. No help at all. Now that I have been working with Safari v.74 for a couple of days, the RAM leak has mysteriously stopped in its tracks! The "Free" memory (white) stays at well over 60% - 70%. There must have been a huge memory leak in previous versions of Safari Beta which Apple fixed in the latest release. Anybody else notice this? jg
