      Description

      The FreeMind Java mind mapping application can hang the X server
      when run on screen 1 (eg :0.1). It works fine on screen 0 (eg :0.0).

      The mouse still moves but all actions such as key presses and button
      clicks are ignored. The solution is log in remotely and kill the JVM
      (using SIGKILL, since SIGTERM isn't enough)

      The problem is easily reproduced, download and run FreeMind:

      <http://freemind.sourceforge.net/>

      Then:

      1. Create a simple mind map
      2. Drag one of the nodes to another node
      3. FreeMind and the X server hang

      It's 100% reproducible for me running either Java 1.5.0-b64 or Java
      1.5.0_01-b08 on JDS3 or CDE on Solaris 10 on Sun Ray or local desktop.

      This was taken on a Sun Ray but the problem has also been seen on
      standard Solaris desktops. This problem doesn't occur on Java 1.4 (eg
      1.4.2_06).
