This may be an issue with Java apps, probably ones developed in certain ways. It only occurs when interface items are placed over a part of the Limewire window.
If this happens to you, try option-clicking out of Limewire to hide it (or, of course, choose Hide Limewire from the Limewire menu, or type command-H). This should remove the redraw problem, as there's temporarily no Java-generated user interface to be drawn, interfering with other UI drawing.
I think. ;-)
