I've started to notice that the longer I keep Word open/in use, it just drains the RAM. Doesn't release it after you close it either - not right away anyways, sometimes I reboot just to free up the ram. Was curious why it uses or ties up so much ram? With nothing else open, it eventually falls to around ~2GB and below, total free available - normally floats around 3GB, and when multitasking with safari (several tabs open), stickies, external backup connected and dictionary my ram falls well below 1GB available, to around 300-500MBs, but without opening Word (everything else on), I *believe* it floats around 2GBs+ still available, I forget the exact figure, but I know it's well above 1GB still free. I have a total of 4GB (the 8GB in my sig is on the way). The mbp doesn't slow down or anything, keeps working flawlessly, but I know at that point it starts to use the HD for lack of ram, and I'm curious as to why Word needs to tie up so much of it in general.
