The new size of the window is much better! I haven't quite figured out how to use the special - I've only manage to use it once. Most of the time it doesn't appear on the list of actions, even if I have full MP.

It doesn't work for me anymore. Some of the filenames have the wrong case. You should rename all the files ending with ".JPG" to ".jpg".

Not quite sure what you mean. But a scenario is identified by the scenario name and the account that is used for the upload. If you want to replace an existing scenario with something else, just make sure you give the new scenario exactly the same name as the original, and use the same account to upload it with. Was that what you meant? Btw, it might be better to ask this kind of question on: http://groups.google.com/group/greenfoot-discuss
