The GraphicsTest demo applet from j2sdk1.4.1 shows a paint error on Windows XP. To reproduce load the applet with StarOffice 6.0. Then put the window in the background, so that the applet is obscured. Then get the window back in front by using the taskbar. The upper part of applet, the panel containing the buttons an choice control will contain part of the window that previously obscured the applet. A similiar behaviour shows the DitherTest applet. This bug can also be reproduced with Internet Explorer and Mozilla 1.01, both using java 1.4.1. The bug does not occur with java 1.3.1 but with 1.4.0 and 1.4.1
