Hi, 

remember un exposed pcb cant normaly developed -it should stay on 
i think either you carying the pcb in the sunlight :) ore your fluid 
is to strong. 
to test that is simple just put a peace off new not exp. pcb in 
developer it must stay on. 
so you must be making somewere a mistake

i had one off those sunlights - as i remember it also had ird ceramic 
heaters!  - worked perfect
