Whoops about the preferences. I'll get on that. *Done*
When it comes to space being play...
In the original JP ver's interface file, space was never such a key attached to that command.
In fact, the first time around, I thought it was /my/ mistake, and I hacked the shortcut key in, but... I don't know. If it's not showing up as a shortcut key in the /original/ English lproj files, I don't think I'll be hacking it in anymore.
Nevertheless, newest ver is up for grabs.
