I have created a simple single page website (using Serif WebPlus X2.) It can be accessed from a link on the main website that I have created for a client.
http://www.southamptonphysiotherapy.com/Notice_Board/index.html

It is intended to allow the client to be able to add text using the free Nvu editor (At present v1.0)

If this website is uploaded in Nvu (using 'Open web location')it displays an odd behaviour. Clicking anywhere outside the yellow 'notice' causes it to disappear. Clicking on the 'Walnut Tree Physiotherapy' object (top left) makes it reappear.

This does not happen in the WebPlus editor.

I would be grateful for any explanation of this behaviour.
