Drawmode is not a gconfig command.  In other words, drawmode takes effect
immediately, rather than the next time that gconfig is called.  I'd guess
that the gconfig implementation on your Personal Iris is reseting drawmode
as a part of its operation.  Try the sequence

	win1 = winopen("Win 1");
	drawmode(OVERDRAW);

	win2 = winopen("Win 2");
	RGBmode();
	gconfig();

This should be all that is necessary.
