An interface with Swing (or probably any lightweight components) is corrupted in the area under the cursor when the mouse button is pressed on a control. The ONLY occurs in some non-default Win98 desktop themes that redefine the standard cursor graphics, for example, the "Travel" theme. However, in these themes, the corruption occurs every time the mouse is clicked. This also affects dragged objects, like lightweight scrollbars.

Some non-default desktop themes cause the cursor to momentarily disappear when a control is clicked. (Maybe some Win98 cursor/mouse action is unmapped?) When the cursor is redrawn, the graphics in a rectangle surrounding the cursor are corrupted, usually drawing a clip taken from elsewhere on the window.

It appears that the problem is related to the fact that the cursor temporarily disappears when the mouse is clicked. This doesn't occur in the Win98 default desktop theme, so the problem may not be commonly noticed. However, normal Windows apps work correctly with these alternate desktop themes, so I feel this is a Java lightweight component bug.
