Hi, Michael. I am very glad to receive your answer! Don't worry about transliteration. It's OK. I wish to thank you for NXTalk. It's refresh my interest for NXT platform and Smalltalk. Today I downloaded last version NXTalk package(NXTalk-mha.137.mcz). After that I started NXTRadarTest and it's works!!! Hurrah! But now Bumper application break down. It's say something like 'unknown primitive'. I think it's because incompatibe version of VM(I have version 0.7). I try to download new version from NXTalk project webpage. But its 0.7 too. Anyway you did a very good work with NXTalk. And I hope to see version 1.0 of it. By the way, do you now about WooWee RS-Media robot(http://www.wowwee.com/en/products/toys/robots/robotics/robosapiens:rs-media)? Its a humanod robot toy with embeded Linux. I think it will be very intersting to program this thing with Smalltalk. Best regards, Andrey.
P.S. I am sorry for my english. I now it's not very good.
