That should not be the case, in fact here is the script uses on the client
side
Mouse_Event_Script : constant String :=
"(e.clientX - e.target.offsetLeft) + '|' + " &
"(e.clientY - e.target.offsetTop) + '|' + e.screenX + '|' + " &
"e.screenY + '|' + e.which + '|' + e.altKey + '|' + " &
"e.ctrlKey + '|' + e.shiftKey + '|' + e.metaKey + '|'";
I am correcting for offset as part of the event message.
Are you finding this is the case in actual tests? I'll go back and test
again, but mouse events should be relative to the element they are set on.
