Selectbox Options limit

System

Hi all,
Does anyone know if there is a limitation on the number of options there can be in a MDC datacapture.cfg file? I have to pull a list of all the states in the world into a multiselect box and I get an error. If I reduce the number to say about 200 or so, it works. I can keep doing that to find out the exact number, but that will take too long so I was wondering if any knew of this "limiation" and any possible workarounds.

Thanks in advance,
Mukesh
