failed to operate on GUI form when invoked from shell

Hi,

I wrote a skill script which can display a GUI form

It works fine if I invoke ocean and load it. I can click the buttons on the form.

However, when I tried to load the script via shell script, the GUI form just poped and then got closed automatically before I can do any operation.

The shell script is like this:

#!/bin/csh -f

cd $DESIGN_ROOT
ocean-6.1.6.500.3 <<EOF
load( "pop.il" )
exampleOpenForm()  #function that display the form
EOF
echo "done"

Could you please help about this?

Thanks very much.
