I secretly updated 0.3 behind your backs several times yesterday with small bugfixes, and there are a few more in 0.4.
Bug fixes:
* Main window now better at keeping the focus in the input widget.
* Call octave_exit() before exiting otherwise on some computers it consumes 95% cpu.
* Keep the files tab synced with the cwd.
* A few more bugs I forgot.
Known bugs (help me if you know how to solve them!)
* QDirModel still is causing me problems. It ignores the NoDotAndDotDot flag.
* I was unable to get the QT assistant configured to work with my HTML
help files. In June 2005, John Vilburn noticed that helpdemo was not
part of the QT distribution
(http://lists.trolltech.com/qt4-preview-feedback/2005-06/thread00304-0.html).
It appears that this is still the case, in disagreement with the QT
documentation.
* If you hit F1 for help, I execute firefox to read the doc. However,
in some situations, you won't be able to close Octave GUI until you've
closed firefox. This appears to be a QProcess feature.
