Folks,
If you use the map viewer in IE7 you’ll find that changes to the layer transparency are simply ignored.
To reproduce, move the blue marble layer over the country boundaries layer. Country boundaries disappear (as they should). Now try and make the blue marble layer transparent. Selecting a level other then Opaque is simply ignored, the selection stays on Opaque.
In Firefox 2.0.0.15 this works ok, the blue marble layer becomes transparent and the country boundaries are visible. I can verify by setting a breakpoint that the event handler (function im_layerTransparencyChanged in im_layers.js) gets called. Setting the same breakpoint in IE7 fails to stop the code.
Do any of you client side gurus know what would be causing this? The controls are being created and are visible. For some reason the event handler mechanism is failing. Any ideas?
Regards,
Stephen
