As Ken Brown has explained, double-clicking bash.exe does not set the PATH.

You should run it from the "Cygwin Terminal" shortcut, which starts a 
login shell, which reads profile scripts, which set the PATH appropriately.

setup cleans the PATH to start with '/bin:/usr/sbin:/sbin', and contain 
any directories in the existing PATH which start with the windows system 
directory (e.g. '/cygdrive/cWindows/System32')

Again, having an incorrect PATH doesn't reproduce the problem of the 
script freezing, so I don't think this is the underlying cause of the 
problem you see.
