Works for 10 minutes and then blacks out
 

I just got my Kensington Universal Multi-Display Adapter and was happy to connect a second display to my MacBook (OSX 10.8). Installed the drivers and everything worked....for about 10 minutes.

Then second display went black for a second, all the windows on that screen moved to my main screen. I moved them back, but blacking out keeps repeating at random intervals. Arrghh. Drives me mad. Just as I am focusing on something...black out...over and over again.

Couldn't take these constant interruptions any more and turned my second display off

I guess this is a driver issue. Maybe OSX is too new. Is that so? Is there a fix coming?
