Martin, Many many thanks, I did post here also so someone would tell me whether using Python was feasible or not for this project (ex, having tkinter or wxPython running prior t oan actual X11 session). Also I did not know about comp.windows.x. Regards, hg -- http://mail.python.org/mailman/listinfo/python-list
