[OpenLayers-Users] Handler problems

[Tom (JDi Solutions)]

I still can't work this one out, any help would be appreciated.  Here's a
live example:

http://demo.jdi-consult.net/oltest/clickprob.html

When the map first loads you can click and hold to pan around.  Select "get
Co-Ords" and you can no longer pan that way, instead a click on the map
displays the co-ordinates below the map.  Now try to click on "navigate" in
FF it will show the co-ordinates of the point you clicked, then on the
second click it is possible to select "navigate".

It works fine in IE6.

Can anyone help?

cheers,

Tom
