Voice chat Bug

[BinaryCrash]

i submited on graal support this bug, but no one answered,
so i will post here, the ticket is there for 6 days... :/

--------
Sometimes when i use the voice chat on graal it freeze my computer. if i press T to talk testing in Options and i click to move the form and hold the button for 2 seconds and then i free the button it stop the sound when moving the form and play the buffered sound after i free the mouse button, so if i dont free it then it freeze my computer like when in game.

I think it's a overflow problem.
I use Win98 SE. 160 ram, pentium 3 500mhz
SIS 7018 Audio Driver.

Thanks for helping.
