Necessary thing, will understand a bit later, Thank you, thank you, thank you

There should be a warning at the beginning of the article that the latest Opera Widgets SDK (0.2) includes a newer version of the emulator than is linked here.

I don't really understand this, but on the computer I'm on at the moment, the emulator doesn't work. When I unzip the package and open the widget by dragging it into the browser, it opens and then displays the "there's a problem with widget/config.xml" error, even though it's fine. I also tried hacking the emulator.js function by creating the xml directly and then it loads, but doesn't sense any events.

I've never seen this behavior before today..

I want to share a problem I had with the Emulator and its solution:
Last week, I downloaded Widget SDK and tried to run the emulator opening the index.html at \opera-widgets-sdk-0.2\util\emulator and Opera browser complaint about "var widget is not defined". Of course, the solution is simply read carefully the article: you must drop config.xml in the same folder to an Opera browser window and everything works flawlessly.
