Does this help?

IDL> plot,cos(indgen(100)/7)
IDL> device,get_write_Mask=smask
IDL> print,smask
255
IDL> device,set_write_mask=0 ; DO NOT WRITE TO ANY GRAPHICS PLANES
IDL> xyouts,50,0,'My string of text',wid=wid
IDL> print,wid
0.131250
IDL> device,set_write_mask=smask ; WRITE TO ALL GRAPHICS PLANES AGAIN..
IDL> xyouts,50,0,'My string of text',wid=wid

You could probably also do this with
device,set_graphics_function=something. Table 3.4 in my online help...

best of luck
