The form I've created contains a pageframe with several pages, each of
which accomodating at least one dropdown list box. None of these
controls seem to work properly when I try to scroll through the lists
by using the mover bar instead of the up- or down-arrow. The displayed
lists only get refreshed when I let go of the mover bar. Needless to
say that not seeing the immediate effect of changing the mover bar's
position makes this type of navigation pretty useless. At the same
time, I would really need this feature to work since I expect the
user to scroll through as many as 800 records at any given time.
The rowsource is a field in every case I use a dropdown list box.

For the record: I have used dropdown list boxes in the past without
ever running into this problem. For the life of me, I can't figure
out what maybe so different with the form I am working on now. Also
it should be noted that after running the form with the problem I
described, other forms with dropdown list boxes will behave the same
way, eventhough they worked fine before!
Please help!

Thanks
Andrew
