Pinta 1.3 on Windows XP:
From menu Effects/Adjustments select any effect. Window opens in the middle above image. User is always forced to move window to one of the corners to see the image and what effect will have when some sliders are moved. I always move windows to the top-right of the window. I suggest to change default behaviour of effects/adjustments windows: top-right.

P.S. This is more an enhancement then a bug.
