I've got a MBP connected to two 2412m's. one with displayport -> dvi and the other with displaylink.

This was working great with both monitors in portrait mode, until I adjusted the monitors in the Display / Arrangement panel. My arrange screens panel is empty, even though the three windows show up on my main monitor if I click the gather windows button.

Both of the external monitors still show an image, but I cannot move my mouse to them. I can use keyboard shortcuts to move windows to the screen, though.

I tried a few different things, the only thing that worked was changing the rotation on the displaylink monitor to be standard. Changing it back to portrait makes the arrange screens empty again.

Anyone have any ideas?
