crashing graal

[Warcaptain]

my graal crashes at seemingly random times.

most times it occours:

1-when i first log onto a server, if i take a step or two it freezes
2-when its loading stuff from the server

it freezes and lags my computer and then at some point illigal ops.
now this freezing crud doesnt bother me that bad
its just i have to restart my computer EVERYTIME it happens.
and when it happens, afterwards, i cant load anything that uses video or something ie: windows media player


so please fix this, its so annoying
and its not like it happens on certain servers, it happens everywhere.
