Hi Offray,

you can use the phratch mailing-list to ask specific questions:��phratch@googlegroups.com.

About your problem of MNU. Could you provide more information. I cannot reproduce your problem:
- I downloaded phratch 4.0 from here:��http://www.phratch.com/phratch/phratchinstall
- run it
- click on the category "operators".
It works for me.

For your second question:
There is a block "clean pen trails" that erase all the��drawn��lines.


I will be happy to answer other questions :)

Best regards,
Jannik

Hi all,

Today we started to use phratch to a group of people without much of any experience with computer programming. The idea is to have a workshop today and tomorrow start with more symbolic and abstract approach using Pharo and give them a taste of the several levels of programmig and exploration this environment provides.

But my main problem is that operators dont work on Phratch. We get a MNU as soon as we select the operators button which is a real stoper for any advance stuff. We're using the currently available package from the download page. Can somebody help me on this?

Also:

��How can we erase a line drawn with the pencil on the background?

I will be sharing more questions as they come.

Thanks,

Offray
