Matlab ignores $DISPLAY on Linux via ssh

Hi all,

when connecting to a server using ssh and starting Matlab with the command

    matlab

only the splash screen opens in the current display. Matlab desktop always opens on the first local display, e.g 0.0. Prepending

DISPLAY=localhost:10.1 matlab

which is the second display does not work either. Still the splash screen opens on the correnct display, but the desktop always sticks to display number one.

Any ideas? Server as well as Desktop are running Ubuntu 10.04.
