I think I know the answer to this question, but I don't have a Server Advanced box in front of me right now to prove my theory.

My question is if I create new tabbed interfaces with FMP8 Advanced, what will happen when I attempt to host those layouts with IWP?

I didn't care for this tool when I first saw it but it's rapidly growing on me. For those of you who haven't tried it, download the trail version of FMP8 and give it a try. It works just like you think that it should and that's the beauty of it. The only downsides are that you can not customize the buttons, and it requires a work around to work with most back button rountines.

You'll need FMSA8 to render the tab control. In FMSA 7 IWP you'll get a big black rectangle where the tabs control is...

With plain-old downloaded trial 8, I'm getting layout tabs over IWP to work mostly fine, no need for server advanced. Mostly, I'm amazed IWP works as well as it does so far.

Yet there's one frustration: There's no way to script a move to another tab. I can make a script accomplish this in the standard FM8 interface by using a "go to field" step -- with some dummy field available only on the desired tab. But the same thing doesn't work over IWP. I trigger the script via button, and the same initial tab is still selected at the end of the script.
