Hi Jim,
you are right.
sorry for confusion.
the Bridge object was created. but sitting up the environment needed X Window for some reason (actually what for?)
IDL> a=obj_new('IDL_IDLBridge')
% Loaded DLM: IDL_IDLBRIDGE.
IDL> a->execute, '@' + pref_get('IDL_STARTUP')
% IDL_IDLBRIDGE Error: WINDOW: Unable to open X Windows display.
Is your DISPLAY environment variable set correctly?
% Execution halted at: $MAIN$
IDL>
this works if DISPLAY is ok.
Boris.
