Can't resize OW window after waking from sleep
 

This problem has existed in OW 5.5 as well, and continues to exist in the 5.6 Sneaky Peeks.

When I wake my PowerBook G4 1.67GHz, running Mac OS X 10.4.10, from sleep, and I've attached an external monitor such that the display size is now changed from the PB's built-in LCD's resolution to the resolution of the external monitor, I cannot resize the OW window, either by dragging the size widget at the lower right corner, or by clicking the +/- widget in the upper left corner.

The only solution is to quit OW and restart it, then resize the window.
