No thunderbolt display while using the display link with 10.7.1

[bluen25]

I have a 2011 13" Macbook Pro with the Thunderbolt port and the latest Lion update, and the DisplayLink 1.7B3 Driver. I have started to experience problems with my main display while I have the DisplayLink plugged in. If I reset my PRAM both monitors work fine. If my monitor goes to sleep I cannot get the display plugged into the thunderbolt port to wake up. The computer is recognizing the second monitor but the screen is still asleep. If I unplug the displaylink the second monitor wakes up. If I plug the displaylink back in the monitor goes back to sleep. Any help would be appreciated.

I have run the displaylink debug tool and attached the file.

Thank You
