Hi,

I have a USB monitor and have installed the DisplayLink drivers. I am not currently using the monitor, but the DisplayLink driver still managed to bring down my system. For the last couple of days, I've had weird display artifacts on my screen. Today, during one of those artifacts, the system went down.

Can a DisplayLink dev take a look at this please?

I'm uploading the crash dump here (I'll leave it up for a couple of weeks or so): http://ottawagamelan.org/aa/MEMORY.7z

Here's the basic info. It appears that I have the latest driver installed (7.4.51572.0). I'm running on Windows 7 x64 SP1.

Thanks,
Alnoor
