[OpenLayers-Users] Scale on the map in nautical miles

[Markus]

Dear OL-Specialists,

How can I make this (webbased):
- window (for tools, dialogs) should be on top of the map every time
- focus should be switchable on map or on tool-window (by cursor-click)
- possibility to move and zoom the map /under/ the tool-windows
- possibility to activate markers in the map, without disappearing 
tool-windows
- possibility to move the tool-windows on the map (it works)
- possibility to make inputs in the tool-window (it works)

Now, if I click to the map, the tool-window disappears behind the map...

Thanks a lot!
Markus
