Crashes to desktop with default DC-3

I've found two mouse clicks that send my FS2004 program crashing to the desktop: (1) On the kneepad scroll bar or anywhere within the kneeppad window. Occurs with either the default DC-3 or the M.A.A.M.-SIM DC-3.(2) On the clock, the lower-left-hand button (hour), only on the M.A.A.M.-SIM DC-3. The other three buttons work fine.I can work around the kneepad situation by using the mouse wheel to scroll, but have no approach to the second.Has anyone else experienced these crashes? Have a fix?Many thanks,Gary
