i switch back to 2.3.8 now it works pylint version 1.5.4 now on spyder 2.3.8 (working one)
old one was pylint version 1.5.1 on spyder 3.0.0.dev0 ( not working ) it was broken maybe pylint was outdated it came by packaged from winpython so i did not checked sorry for disturbition.

problem was i could not copy values from variable explorer.this pic belongs to version 2.3.8 for demonstration porpose ,in version spyder 3.0.0 dev0 there was also history there
