I have never heard of this happening, so it might be foul play. I'm not sure how you would hide the draw deck off the window... perhaps by grabbing the farthest corner and dragging it out of the screen by one pixel. Too bad you can't check in retrospect to see if you could still draw cards (by typing d1, d2, d3, etc.). I'd suggest talking to wlk if you suspect anything, and he's the one (if anyone) who could change the core behavior of the program. Remember, GCCG is used to play various games, so the sort of thing as limiting who moves what deck is probably defined in the base program, not the LotR module.
