I seem to be unable to move the camera downwards when I put my mouse to the bottom edge of the screen.

I can move the camera to all the other directions without any problems but to get my camera to go downwards i have to either use the keyboard button for moving the camera or work with the lower corners and left/right side of the screen to get the camera where i want it.

I like using mouse for camera movement so this is a bit of an annoyance to me.

Is anyone else having this problem and has it already been reported or in the process of getting "fixed"?
