[OpenLayers-Users] OpenLayers 2.13-RC2 hangs in IE and Chrome on zooming/paning

Mon Jun 3 02:04:59 PDT 2013

Hi Bart

I tried to use RC5 and using the TileManager, we can still provoke the
browser to freeze, both in chrome and IE, but it  require more violent
movement and zooming at the inner most level to trigger the freeze (we use
the code in 1).

However if we modified the code to 2) (adding transitionEffect=null,
zoomMethod= null) then it freeze when drawing a rectangle to zoom at the
last zoom level both in IE and chrome. 

Any ideas?

I'd suggest looking at what Andreas suggests here:

https://github.com/openlayers/openlayers/issues/991

Please try it out and report back. Also please try the latest RC so RC5
instead of RC2.

Best regards,

Bart

Hi

We have a customer who use IE10 and then we tried to upgrade the OpenLayers
to the new OpenLayers-2.13-RC2 to get around the grid bug in IE10. However
when zoom fast around in both IE9 and chrome (27.0.1453) using only the OSM
layer as baselayer the browser get stuck and we get the "long script
detected" dialog to kill the script. We have found at the inner most level.
Have anybody else seen this problem? I have not tested it in IE10.

We use the sample code to test with:

<!DOCTYPE html>

    <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
