Ok, then here's an idea for a hack around the bug: Directly before the "real" 
dev.off() add
   .rk.lock.device <- TRUE
and
   .rk.lock.device <- FALSE
directly after. In rk.screen.device add
   if (exists (.rk.lock.device) && .rk.lock.device) return
at the start. I also have another potential solution in mind, but perhaps this 
one will work for you.

Just make sure it gets called, I can take care of the implementation (it will 
collect info on the number of plots in the history, and the history positions 
of each device, and pass that on to the GUI; if you want to take a look at how 
to send info to the GUI, you can try to follow the code path of 
rk.screen.device, but be warned that this may be a bit ... non-obvious).
