Hello

I use Drupal 6.17 and Mapping kit 6.x-1.x-dev, OpenLayers 2.8 and it's working very well but I found problems when I try to open page with map and gpx track on it with IE8 and Chrome browsers.
In Firefox all is working.
In IE8 when I open the page, map area is empty - not a map or track, and IE8 show error icon on bottom left corner and have this error:

Message: Expected identifier
Line: 363
Char: 15
Code: 0
URI: http://www.phreedomnet.org/tracks/node/45

Message: 'a' is null or not an object
Line: 1
Char: 1
Code: 0
URI: http://www.phreedomnet.org/tracks/node/45

When I try to load your demo page for "Overlay maps with GPS tracks" http://aardbodem.nl/node/37 I have the same problem.

I try to debug with IE Developer tools http://aardbodem.nl/node/37 and receive this:

 Expected identifier  37, line 247 character 15
 'a' is null or not an object  eval code, line 1 character 29058

First error go to this line in page source:

247: style_options.default = OpenLayers.Util.extend({}, OpenLayers.Feature.Vector.style['default']);

Second error go to this on "eval code":

return a.call(this,D)

I try to change on my site OpenLayers to version 2.9 and the problem still exist.

Strange, now I try with Opera 9.6 and have the same problem.
Before some time I try the same with old version of Opera and it works. Perhaps this problem occur after some browser engine changes but for now I can't found how to make it works again.
