> 1. button "Update Comets" - this will download the comet file and

> 2. checkbox "Display MPC Asteroid"
> 3. button "Select MPC Asteroid File"
> action 1. - if user select checkbox "Display MPC Asteroid" to true,

> turn off.
> action 2. - if user select checkbox "Display MPC Asteroid" to false,
> button "Select MPC Asteroid File" is disabled and Guide asteroids are
> turn on.
> Guide retains the selections on shutdown.
> On start if Guide, with "action 1" above active, does not find MPC file
> then Guide displays nothing.
> if action 2 on start and Guide Asteroids not installed, Guide displays
> To summarize, we have 2 choices, first one is to display Guide asteroids
> from the DVD if installed or access from the DVD.
> The second option is to use MPC asteroids from a downloaded file of our
> choice (MPC format).
> No other asteroids except those in the selected MPC file are displayed

> As for rebuilding the asteroid cache, I don't mind waiting a few seconds
