      Carlos.Lucasius@Canada (June 24, 1998):
      This bug was initially reported for JDK1.1.5, but it
      can also be reproduced in JDK1.1.6 and JDK1.2beta4.

      Description follows:

      Compile following java as test.java.
      Run in appletviewer.
      Select "Disable Me" button
      (Note button is frozen in depressed state.)
      Select "Enable Him" button.
      (Note that button is visually depressed initially
      and after mouse moves over button, visually not
      depressed after mouse moves off of button --
      even though no mouse button is pressed.)

      This happens only on Solaris (appletviewer and
      Netscape 4.05 w/ Java 1.1 Plug-in). Does not
      happen on NT (IE or NS).
