infoBox issue: html form inputs are render but not editable by user

[GoogleCodeExporter]

Goal: I was looking to use infoBox to easily reference geo-cords info, for 
attachment to additional content to include in my map database via a form 
contained in the infoBox. The form renders and can be updated via javascript, 
but can't be actuated by user. Basically forms inputs don't, ALL, work in the 
simplest of infoBox.

What steps will reproduce the problem?
just add a simple form into 
boxText.innerHTML = "<form name=SubmitFormName id=SubmitForm action=# 
method=post ><select 
><option>1</option><option>2</option><option>3</option><option>4</option></selec
t></form>";

Expected result:
html form inputs are render and editable and submit-able by user

Actual result:
html form inputs are render but NOT-editable by user. Check boxes work, as well 
as submit button, but that's is it.

Version: tested with InfoBox 1.1.2 & 1.1.9
