I created a standard tabular form using the wizard, and then I changed the first displayed column to a select list. In this case, the dept no.
In Firefox 3.6.6 and 4.0b1, every time I refresh the page, the value of the selection list change. It is odd. Doesn't happen in IE8.
To reproduce the problem, run this page in firefox, hit the refresh button 10 times slowly and watch the Dept select list changing.
