We haven't changed anything on our site; this is purely due to a Chrome update. We are still investigating what can be done to make our site work with Chrome. Initial work revealed it was complicated and would take some time to resolve. We're sorry for any inconvenience.
Now CodeBug is connected to your computer, much like a USB memory stick, you can drag your program onto CodeBug. Find your downloaded program file, and drag or copy it into where CodeBug appears on your computer’s folders.
