ever since i've formatted my machine, i've noticed a strange phenomenon. it seems like my powermac is always running out of ram, because the system starts to slow down dramatically. i've never had this happen before, since i'm running off 896 MB ram and it was not a problem before i formatted. right now i'm running photoshop cs, illustrator cs, safari, textedit and suitcase x1 and there's only 13 mb of ram free according to activity monitor. anyone know what might be eating up my memory?
