Pop up menus - Blu ray

I am not currently running Encore (I use DVD-SP for DVDs)... but with the current ongoing project over at Rivergate with Blu Streak being able to take Encore builds and create replicatable projects I am currently assessing the various softwares for Blu ray

I understand that Encore has now implemented pop up menus but I seem to recall reading somewhere - can't remember where - that it didn't do them "properly". That is, you can create pop up menus but if you want a menu that has the chapter screens and you want say, five on a screen at one time and it to then "roll over" to the next five, that Encore can't do this. is this the case or can it create pop up menus properly in the same way that they work on all commercially available Blu rays?

Many thanks

Steve
