• Redraw Error
    Sometimes the display shows some white parts during a move or even after a move. Just select "Miscellaneous/Redraw CRT"
  • Race Condition
    In rare cases (about 1%) the evaluation is not always the same and differs by a small amount. I assume a race condition and will look for a fix after the release.
  • User provided Random Plugin
    would work, if I hadn't forgotten to include it. Will be in 2.9.2. Sorry 'bout that.
In any case, if you find some strange behaviour, I recommend a fresh install. If this doesn't work, just drop me a line and include a description what is happening and the log.txt from the installation directory.
