dabbrev not to create a new window

[Dan Cardamore]

I'm using dabbrev and I'd like to have it show me the possible
completions without splitting my window in half.  Currently it does
this and puts the possible completions in the bottom half of the
screen.  Once I've chosen one, that screen stays there rather than
closing.

I'd prefer to have it go away once I'm done, and have it take as
little space as possible rather than always taking 50% of the screen.

Does anyone know how to do this?

Thanks,

Dan
