Yeah, there's not much that we can do about that (that I'm aware of)...
Perhaps this is the "correct" behavior, but I found it disturbing to be suddenly taken from an Inkscape window on my root-screen to a Time Machine backup alert window (ie, I haven't backed up in ten days---bad) on my Desktop.
I find that several times a day my system switches from the X screen to the Apple screen for a fraction of a second - just long enough to lose a few keystrokes and turn "rm -rf /tmp/t" into "rm -rf /" (no, that hasn't really happened, but less drastic things have). Unfortunately it's too quick for me to be able to see any clue as to which program is causing it. -- Richard -- The University of Edinburgh is a charitable body, registered in Scotland, with registration number SC005336.
