Nvidia 266.35 and 266.58 on Win 7 Pro 64bit
 

DisplayLink-5.5.29194 and 5.6 Beta do install and run without any problems on a Win 7 Pro 64 bit with a Lilliput USB-Monitor when having Nvidia 266.35 or 266.58 installed (for GTX 5xx series) .

Until I reboot my computer...then no graphics driver at all gets loaded, I get the incompatibility error and, when right-clicking on the desktop, the famous ATKDispCPL.dll error. I have to unistall DisplayLink to return to normal. :(

As it installs and works fine the first time, I guess this issue shouldn't be too hard to fix...

Thanks for trying...
