Jumping to locations in long drop-down lists

[DarrylGould]

Hello

I have an InfoPath 2003 form which uses a drop-down box, which
contains 7000 entires. The tool works fine, however, the users would
like to be able to start typing the name of the record in the box, and
have the form jump to that entry in the list. At present, if they type
'BE' InfoPath simply jumps to the first entry begining with 'B'. We
would like it to jump to the first entry begining with 'BE'.

Any ideas?

Many thanks
Darryl
