Thanks for the info, Dragan!
Just wondering though...I created a test form and put a pageframe on it with two pages. I then saved it as a class. It seemed to save ok. I modified it with the class browser. So is it just that you can't save pageframes with pages at runtime using Saveasclass?? Also I haven't updated to latest SP. Probably not but just wonder if any different in this respect.
Thanks.
