Facebook makes MOS freeze.

Hi all, I have been using my MacMini 1,5Ghz with MOS 3.2 for a long time now. I use it in my work as a 2nd computer to do testing of webpages and webshops.

I have found it to be very stable and reliable and I often leave the computer on whole days with open webpages,

I have noticed if I leave Facebook open - after a certain time (hours) the computer freeze and need to be restarted.

It can be the screensaver is freezed.

My conclusion is it only happens when facebook is open.

Anyone else experienced this with OWB / Mac Mini?
