Don't know how many people use this little trick, but it comes in handy occasionally.
If you zoom in on a flash window, sometimes the bit you want to see is off the edge of the window, or not centered (you did right click over the area you wanted to zoom in on, didn't you?), and there doesn't appear to be any way to drag the picture around to bring back into view the bit you want.
If you right click again and select 'Settings' from the context menu and then do a ¾ double click on the Settings dialogue close button...
...the cursor will change to a 'grab hand' and then you can drag the image around.
A ¾ double click is the same as a normal double click, but without releasing the mouse button on the second click.
