I don't believe the lab server is seeing your runtime license. When I do
"idl -rt=myapp.sav", I don't get a window popping up, but if I do "idl
-vm=myapp.sav" I do get a window. IDL will default to using the Virtual
Machine (and it's window is the price you pay for using the VM) if you
don't have a license.
