Im trying to get Matlab (R13) to work with a dual monitor Xinerama
setup. Matlab starts up but freezes if I run certain graphics related
programs (toolboxes, GUIs etc). Some programs seem to work (eg.
logospin). No errors are displayed.
This problem seems peculiar to Matlab since other applications work
fine. The same thing occurs in R14 as well.
Any ideas?
