I installed Atelier on Windows in order to take a look at how the BPL and DTL graphical editors accessible via the "Open diagram editor" action work. The diagram editor is opened but I get the following error:

Message from webpage
---------------------------
Unable to load SVG diagram. Please ensure your browser is supported for portal access.

It looks like Atelier uses IE in order to display the editor even though my Windows default browser is Chrome.

I tried to change the General -> Web Browser setting to "Use external web browser" and choosing Firefox or Default system web browser. However, regardless on this change (and Atelier restart), IE is still used for opening the diagram editor, so it seems that this setting affects some other browser usage.

The same problem affects the browser launched for the Atelier Videos site located on the Overview page.

Is there any setting which I could change in order for the diagram editor to be opened using other browser than IE or is this not possible at the moment?
