We are using a the following class to show a progress-bar in our Java application: [TextProgressBar](http://code.google.com/a/eclipselabs.org/p/opal/source/browse/src/main/java/org/mihalis/opal/textprogressbar/TextProgressBar.java?spec=svn0392d56b117520d51a97fd211a4da726e25738d8&r=0392d56b117520d51a97fd211a4da726e25738d8)

Unfortunately we are having some problems with flickering when using that (Win 7, Java 7). Do you have any tips on how we can avoid that? Can we somehow repaint it less frequently, use double-buffering or something else? Any tips are greatly appreciated!
