<div class=Section1>
<p class=MsoNormal>I have been having an on-going problem with OL (using 2.7
and same in the trunk). The issue seems to only occur when using IE. If you
disable the zoomWheel in the Navigation control and then load a Control.Click with
an event script to capture clicks and mouse positions in a map. Show this map
in IE and then scroll with the wheel over the map panel itself the browser
throws a this.element.scrolls is null or not an object. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I looked at the event script and I believe that during the
getMousePosition function the evt is being destroyed with the
this.clearMouseCache event (caused be scrolling using the wheel over the map).
I know I am close because I wrapped the whole getMousePosition function is a
try { { catch{} and the error has gone away. I would debug it further however I
cannot use Firebug in IE as I do in Firefox. I also find that IE does not launch
my debuggers correctly in this instance. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I know it is killing the event (this) because if I comment
out the this.element.scrolls section lines 777 – 783 the error is
reported then against the this.element.lefttop. Is there a better solution?<o:p></o:p></p>
