I realize that we could potentially have a zillion of these compatibility-checking threads, but...
...is anyone running MATLAB 7 on Tiger?
MATLAB 6.5 broke pretty bad on Jaguar, but it seems that that was merely the transition to an Apple-official X11. I presume (hope??) that there won't be similar issues with moving to Tiger. If there are, I have to wait to upgrade until the semester's over.
