[ka-Map-users] Problems with addObjectGeo again.

[Samuel Doyle]

Perhaps it has something to do with the various style sheets and such that are being used. Guess I'll just need to overcome it via brute force but even doing this still results in a lot of drift when viewed on different scales.

S.D.

     e = (e)?e:((event)?event:null);
     var x = e.pageX || (e.clientX +
         (document.documentElement.scrollLeft ||  
document.body.scrollLeft));
     var y = e.pageY || (e.clientY +
         (document.documentElement.scrollTop ||  
document.body.scrollTop));
     var a = this.adjustPixPosition( x,y );
     var p = this.kaMap.pixToGeo( a[0], a[1] );

and haven't run into any problems

Cheers
