I wrote a cellular automaton project, but while it's fine in Scratch, it doesn't work on the web site.
I distilled the problem into the demo below:
http://scratch.mit.edu/projects/ukslim/6459
Essentially I am trying to detect marks on the background by moving a sprite onto them and using "Touching color () ?".
In the sample, on my own machine it correctly counts three neighbours, but on the web site it counts none.
Could I do something different, or is this a bug in the applet?
Thanks,

John,
I seem to be having a similar problem as described here:
http://scratch.mit.edu/forums/viewtopic.php?id=361
whereby I put a mark on the background and then show it changing. This works fine on my machine but fails to work in the online web version. This must be related in some way and must be an applet bug of some sort.

If it works in Scratch but on on the applet then it is a bug :-)
It would help a lot to isolate the problems you find with the applet vs desktop behavior. If you do that, we could get it fix much sooner!
Thanks a lot for reporting this guys.

The bug seems to occur with the "is touching color" command if the color (or detecting sprite) is smaller than 4x4 pixels (the size of the grey and white grid boxes in the picture editor) or a line thiiner than 4 pixels wide.
