Please note that the graphical user interface is still a bit rough around the edges. The GTK+ user interface toolkit is still in an early development state for Mac OS X. The user interface may be sloppy or freeze for brief periods. There may be glitches in the graphical output. You can minimize these effects by not tinkering with the dvdisaster window while any actions are in progress. Especially avoid resizing the window and sending it to the dock.
During the 0.73 development cycle some workarounds for these effects may be implemented; otherwise the plan is to wait for improved versions of the GTK+ toolkit.
There are no plans for developing a dvdisaster version not depending on GTK+ as this would mean to completely re-write the program for Quartz. Similar reasons hold for the Windows version btw ;-)
Caution: dvdisaster can NOT be installed from manually unpacking the setup.exe program, or by copying it from an already existing installation. Doing so may result in strange errors which seem to be totally unrelated to an improper installation.
