PS quits everytime I do something

[sun_and_moon]

I have an annoying problem. I log into PS and I get into the world just fine. I can move my character and chat, but everytime I do an action (open a window, for example inventory) or cast a spell/mine for gold, my game quits! It does it every single time and it wasn't like that for the first bit of me playing on the new Mac release. Now it doesn't go away. I turned on the Vertex Buffer thing but that didn't help.

*Sigh* Since I did not post my system specs I can see why I did not get any help

1.5 GHz Intel Core Solo Mac Mini
512 MB 667MHz DDR2 SDRAM
Version 10.4.8
and my GFX card is Intel GMA 950

Edit: Latest version, did not use Java updater

I wish there was more with mac OSX people.
But even if you can be never sure if there is any help for you.
i'm on Windows and i have some bad bug with too strong shadows everywhere in hydlaa, so many things are just black and it is hard to say what is the exact problem. But itr is nothing compared to a crash.
