Client crashes randomly

[Atmas]

Client freezes up and can't be used. Attempts to get it going again with ctrl + enter just result in it crashing. These freezes seem to occur at pretty random times, usually seems like when I'm moving but not the biggest sample size. Can go hours without happening.

Getting to the point where it is pretty annoying. Died a few times on different characters because I was in the middle of running or sneaking somewhere and the client froze up at a very inopportune moment. I've ended up with my character running into mobs or having to log back into a dangerous spot that was fine when I was hidden.

Wondering if anyone has any insight on this issue. Currently running the client in Windows XP SP 3.
