I once had to have two instances of browser object on two containers on the same page in a pageframe, and had all sorts of issues with bleedthrough, focus, and whatnot. In the end I resorted to removing instead of trying to hide, and creating a fresh one each time I needed it. It was blazingly fast, and all the issues were gone. That was seven years ago and I guess it still works - it did two years ago.

Yup, popup's the word which I couldn't remember, personal pref... impediment. I never understood why they had separate code and vocabulary for menus, to apply one set for the vertical case, another for the horizontal case. They're the same otherwise.
