Can't move bags

[nerdlyhaxor]

Every time I attempt to move my bags around the screen, by placing the cursor over the square in the upper right corder of the bag window it only gives me a resize cursor and makes me resize the bag. If I make the bag an odd, non-rectangle, shape I am able to click on the "space" and move the bag around. Not sure what is causing this. I have downloaded and installed a newest version.
