I just upgraded wss 3.0 site to sp2010 foundation. Upgrade went fine without any problems. When i was testing the new system i can into a problem with a custom list. When i click add new item in a list it doesnt give me that nice modal pop up dialog box like other lists do in my site. It navigates me to the full page. I checked the list setting-->Advanced Settings->Dialog Option it is set to launch form in dialog.
Is there a way to fix this issue?
Thank You
