Hi all, 

I've been working on Phratch, a port of MIT Scratch to Pharo, mostly to learn Smalltalk and also because Scratch is a great learning environment and I can't bear to see it end up in Flash.

So I've been digging about in the old code to fix bugs and I'm getting a sense that there's some conflict between the way the Scratch team got things working in Squeak, and the way the Pharo team things want things done. 

I must say I think the Pharo team have things right in their drive for a cleaner, simpler system, however that means I'm a bit stuck.

See the attached image of my Scratch script.

Here's where I am...

1. Keyboard events for 'When <key> pressed' HatBlockMorph (with then pen commands) work fine as these follow the regular Morphic event model

2. But 'if <key> pressed' operation (with the stamp command inside) doesn't work because it relies on polling the InputEventSensor, and I think this bit of this class doesn't work as I expect.

My view right now is that for 2, I need to use some kind of polling, and InputEventSensor has methods such as keyboardPeek and peekKeyboardEvent that imply you can poll,

but looking at the implementation, which uses WaitfreeQueue I can see that calling these methods results in events being consumed, hence my post to Stack Overflow...

I've hacked around to come up with something that sort of works, outlined in this post:

http://stackoverflow.com/questions/16495436/saving-modifications-to-existing-kernel-methods-to-monticello

...but I get the feeling I'm doing the wrong thing here, and that I should come up with a solution that better fits the 'Pharo way'.

So, let me know what you think. I'm happy to provide more info and to research better solutions, let me know...

Finally, apologies for the long post! 

Best regards, 

-Eric.
