Thank you for the idea - it definitely works, great workaround. I am going to use another absolutely positioned empty image as an anchor for a menu rather then one wide image, but I would not have thought of it myself.
Since I don't know js and programming, my life is spent in workarounds
I'm sure Andy will do what he can, but I'm not sure what you suggest would work anyway. I'm not really good an explaining 'techinically' because of my lack of programming knowledge but.... the menu you are using is a pop menu, it's not relatively positioned like when you put it in a table, or in a div as many do which makes it 'a part' of that table or div and so follows what happens in that table or div. So when you pop it up it's sitting 'on top' of the various things. Since it is doing that and it's not 'part' of the div that gets the scroll bar I can't think how the menu would know about that. I don't even know if it would shift over if the div that had the image in it got a scroll bar, since it's 'on top' of that div, also, and not a 'part' of it. I hope that made sense.
