    I'm having a problem programming my mouse on a Tandy 1000 TX when using
    Tandy Mode Graphics (Video Mode 9). When I display the graphics cursor,
    using standard "INT 33h" function calls, I get two partial cursor
    images, each one missing every other row of pixels. Both images move
    together as I move the mouse. It appears that if the two images were
    overlaid I would get the proper cursor image. If I switch to some other
    graphics mode, such as mode 5, everything works fine.

    I believe the mouse can be used in mode 9 because I have a Tandy paint
    program that, I think, uses the mouse in this mode. Any suggestions?
