My Dell Latitude E7440 has been functioning great with the Targus dock using the 7.7 beta with the exception of leaving the computer overnight. When returning to it, I move the mouse to wake the displays (computer is not asleep, just turns off displays after 20 min) and the desktop is displayed as it was when I left it. Problem is, everything is frozen. No mouse or keyboard response. I rebooted yesterday and everything came back normally. Same issue happened again this morning, so I tried unplugging the dock and plugging it back in. This had the same result as the reboot. Everything is working fine. So it would seem that the laptop is still working correctly when this happens, but the display link gets messed up somehow. Any suggestions?

Running:
Windows 8.1
2 x Dell 24" LED monitors
Wireless Logitech KB/mouse
