Last week I found that it is no longer an easy thing to add an iframe app to my page. Oh I made the content and put it on the server and created the app just fine. But when I went to add it to my page, well it was half a day to figure it out. Seems that FB was not giving the right info (they do now I think) and the code was not working that was supposed to.
I blogged about this with the complete process and code to make your tab content not scrolly here.
