listbox table problem

I would appreciate a pointer.....

I have an asp page that links to an Access database and retrieves 2500
records and each record line has two listboxes.
Each line is a pallet of stock and one listbox contains what to do with it
and the second is a reasoncode. The user gooes through his/her stock
indicating stock that needs to be disposed of and the entire page is then
updated to reflect these choices.

The problem is, although everything is fine when a few hundred records
are retrieved, when the full
2500 are the listboxes do not position themselves within the table cell
and even extend beyond the table at the bottom of the page. Any ideas?


This is the extreme of the records available and there are filters to reduce
the number of records but this option will still be required.

The server in NT4 running IIS4 and the browser used is IE6.

Many Thanks
