Comment 8 for bug 124562

I still see intermittently on 1.6.0_03-b05 - mostly in dialog (modal) boxes. The sun bug for this is marked as fixed (http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6429775), but there are plenty of recent comments suggesting that it's still a problem.
exporting AWT_TOOLKIT=MToolkit isn't a long term solution, Mtoolkit was replaced by default with XToolkit in java 5, and is likely to be removed at some point.
