InfoPath Dev

I have an Info path 2007 form with lots of controls on them.    Several are multselect listboxs which work just fine providing the form is not set to browser enabled.

 Once I check browser enabled those controls become disabled.    What are my alternatives?

The multiselect listbox is not available for the browser. Please read this for more info:
