Hog2PC: Windows disappear when MOVE-ing a cuelist to a fader

I am using Hog2PC, v 3.3 (177) running on a MacBook under Crossover. When I try to MOVE a cuelist from the list window to a fader, the Hog windows disappear, which causes me to have to quit and re-start Hog2PC. The cuelist I am moving is a chase cue. Has anyone had this experience before?

Thanks,
Dan
