What I am about to describe is something that I have unfortunately been unable to reproduce on demand. However, I'm reporting it anyway in case someone else has had similar problems.
Sometimes, I will hold down the Ctrl key and drag a checker across the board. In the process of doing so---and I think this tends to happen more often when I'm dragging a checker off the bar onto some point---sometimes a blot of the opposite color will get "hit" and will jump to the bar. For example, say I Ctrl-drag a black checker from the bar to the 13pt, and there happens to be a White blot sitting on the 17pt. After I release the mouse button, the black checker ends up on the 13pt as intended, but the White blot will jump from the 17pt to the bar. I don't have to move over the White blot for this to happen, though it seems that the blots that get "hit" tend to be approximately "between" the start and end points of the drag. Some other weird things can happen in the process. I have sometimes ended up with 16 checkers of one color on the board. (It reminds me of a sleight-of-hand artist. Objects pop in and out unexpectedly, and all of a sudden there are more objects than you started with!) At this point there's not much I can do other than to reset the board to the initial or final position, which usually eliminates the 16th checker.
