Hi Richard,

I am not certain of the exact reasons, but I did have the same problem myself once, and it boils down to:

The automatic initialization of $_ happens only if the while loop looks like while (<>)

Anything else fouls it up. e.g.
This works 

# ctrl -c to exit (this is only example code!!!)
while (<>) {
    print "\$_ = <$_>\n";
}

e.g.
This does not work 
# ctrl -c to exit (this is only example code!!!)
while (<> and 1) {
    print "\$_ = <$_>\n";
}
