bringToTop() does not work if some windows has been closed. Example:

graphics.off()
x11()         # opens Figure 2
x11()         # opens Figure 3
dev.set(2) 
dev.off()     # closes Figure 2
bringToTop(3) # Gives an error
# Error in bringToTop(as.integer(which)) : invalid value of `which'
x11()         # opens Figure 2 again
bringToTop(3) # Works fine

It seems that *all* preceeding figures k=2,3,..,K-1 have to exist to be able to
bringToTop() figure K.
