[mapserver-users] Fwd: full extent

[Rob Holloway]

Hi 

I tried the code you supplied but I'm still having
some problems.  The button only works after I have
manually selected my pan radio button - for some
reason the document.mapserv.zoomdir.value = 1;  
doesn't seem to work.  Have any ideas?

Cheers

Rob
