Hello i used this code to select rows of my table...If the selection isnt visible page scrolls... It works great ,FIrefox,Internet Explorer,Safari, but not in chrome..... In Chrome 4 not the last version it worked great!!!

The problem is that return false doesnt prevent the page from scrolling...

Answer 1

try to call:

event.preventDefault();
event.stopPropagation();
return(false);

ALL three.

Kind Regards
