FAQ Section: Weird Bugs
  1. WARNING: Couldn't flush system prefs: [...] Couldn't get file lock.
  2. Poseidon crashes/ ends in a Blue Screen on Windows XP/2000

    Unfortunately, most Java applications will crash whenever they encounter particular combinations of graphics cards and drivers. This usually occurs with old graphics drivers.

    Download and install the latest driver from the manufacturer's web site, or contact the manufacturer or your local vendor.

    Other cures include:

    • Tuning of hardware acceleration (disabling DirectDraw and Direct3D)
    • Disabling Java's 2D-support by adding the parameter "-Dsun.java2d.noddraw=true" to the start-script of Poseidon (found in the bin directory)

  3. UmlDoc just hangs...
  4. I'm having some strange repaint problems...
  5. How can I fix the toolbar display in the Metal look and feel?
  6. Why does type ahead not work in quicksearch?
  7. Poseidon crashes when trying to change font on Ubuntu Linux
