Hi,
We need a little more information to help you.  You can find guidelines for
posting to the mailing list at http://www.ros.org/wiki/Support

Some specific questions.  What displays on the screen? When you say it
"blocks" your OS what does that mean?  What happens if you wait?  How long
do you wait?  What sort of machine are you running? (CPU, Memory)  What
version of ROS are you using?
