Bug 20556 ImageAnalyzer example - bug in the set background
build 20020617 1 - Run the ImageAnalyzer found on org.eclipse.swt.examples. 2 - In the Background Combo choice a different Color 3 - the canvas on center will not changed its background color, only the scrollbar will. The bug is on examples, though this is working properly on Windows. A possible fix is remove imageCanvas.fillRectangle(...) call from the changeBackground() method. Maybe we should fix this to F4..
