I was using 5.3 and had the following issue:

I updated to 5.4b1 and i still have the same issue.
Any chance for a fix? It happens when the DisplayLink software is running, even if i don't have the USB Adapter present.
Also, when i remove the USB Adapter, it disables both of my secondary screens (i have 3 screens, 2 of them are directly attached, 1 is via DVI2USB adapter)
My system:
Dell Precision Workstation M4500
Windows 7 x64
8GB memory
nVidia Quadro FX 1800M
Docking station w/ 2 DVI Outputs
Thanks,
