Never had this happen to me. Since it only happens to some people, we need to narrow down what is different about those people...
i.e.
PC stats:
OS: Windows 7 pro
CPU: Dual core amd
Video Card: Geforce
Connection: Comcast cable
Wired/Wireless(?) - Wired
Optional EQ mods:
High res textures (y/n?) - N
Wineq2.0 (y/n?) - Y
Anything else you can think of?
