grass shell problem in xgrass

We are having problems running the grass shell through xgrass.

What is happening is when grass shell is selected from the default menu
of xgrass, a window opens up briefly with "XGIS.sh" in the title bar then
the window immediately closes. Has anyone had similar problems and if so
any are there suggestions to fix this problem?

Thanks in advance,
Kevin
