Please elaborate on the problem(s) you have encountered. Are they bugs or problems with scripting?

The backdrop has been black and the sprites have had black squares around them.
I also have had problems with cloning. I had two scripts that worked perfect and I didn't do anything to them but they stopped working.

For the black squares, see here: http://scratch.mit.edu/discuss/post/273724/

See this for more explanation about the (ex-)beta player: http://scratch.mit.edu/discuss/topic/32172/

But for the cloning problem, it's hard to say for sure - probably best to share the project so we can take a look…

The problem is, that it is on a game that I am working on and the game is useless without the cloning.

Can you share the game?

How about you write the scripts in the topic? Example:
if <> then
stop all sounds
play sound [ v] until done
play sound [ v]
set instrument to ( v)
set instrument to ((item ((item ( v) of [list v]) v) of [list v]) v)
replace item ( v) of [list v] with [thing]
delete ( v) of [list v]
delete ( v) of [list v]
say []
think [] for (2) secs
think []
show
hide
wait until <>
wait until <>
else
repeat ()






end

end

end

end
I just did random.

Hello. PLEASE check out my projects! They're not all too bad…

OK, if you can't share the project then it makes it rather difficult to diagnose!

But here are a few thoughts…

1. Perhaps you could try to make a stripped-down version of your project that shows the incorrect behaviour? That might help you to understand why it's happening, or it might lead to someone being able to point it out to you.

2. Can you be more specific about the *way* in which it is not working? i.e. what you expect to happen, what the scripts are meant to do, and what is actually happening that you don't expect. Including snippets of the scripts in question in your post (using scratchblocks) would probably be helpful.

3. One of the most common problems clones produce is caused by not realising that all clones of a sprite also receive broadcasts. That means if you have an original sprite, with a couple of clones, then whenever you send a broadcast, the original sprite and those clones are all receiving the broadcast and running the associated script independently of each other, and also simultaneously (if it's not just a non-refresh custom block).
It's very easy for something to happen that you really don't want because of this - for example, if you have clones being created by a broadcast, then it could be that all of the clones are creating yet more clones, when you really only expected the original sprite to create a clone.

Hope there's something useful in there!

I have bee having the same problem with black background. My students have been putting in backgrounds from the scratch library selection and once they have been clicked on - they are showing in the right place on the side bars but not in the main screen . this remains black. There is little scripting in the project as they are just learning how to make them move and change colours etc.

The other issue we have is that the language has been randomly changing in the middle of a session. Happened to more than one kid at the same time so I don't think it was anything they pushed. Also happened to me. I couldn't find where to change it back because I couldn't read it! Later on, it just changed itself back, but logging in and out and refreshing at the time did not make it revert.
