The problem is when the content page needs to perform a form based action and then the master page form tag conflicts with this. I noticed this currently in my site. I have a content page that is doing an action in its form tag. Because there is a form tag in the master page, it clobbers the content page's form tag from doing what it needs to do, move that page out of a master page scenario and it works. I tried removing the master page's form tag but that only caused menu controls to complain. Anyone figure out a reasonable solution to this??
