Thanks for your response !
Sorry, I took a few days to respond.
This screenshot should make it clearer, I hope.

You can see that the menu in the left frame has no right arrow, although I hovered over "Demos .." to open the submenu.
This, I'm sure, is just indicative of the "interesting" way I've handled the navFrame.
Let me also clarify the points I made earlier.
I basically derived my code from
"[UDM] Demos : Popup menus, across frames"
http://www.udm4.com/demos/popup-frameset.php
which has a fairly simply styled, and horizontal, topList, unsuitable for my layout.
So, I've had to restyle the list in navFrame so it looks like a menu. But I did that just by grabbing some CSS from
http://www.udm4.com/udm-resources/ud...ative-left.ini
So, it's the way I've created the list in navFrame that I'm worried about.
I hope I've made that a bit clearer.
I can provide a live demo if necessary.
