Extra newline with bash read?

My shell scripts that use "read" to get user input aren't working.
Here's a simple example:
#!/bin/sh
echo -n "input a1: "
read a1
echo -n "input a2: "
read a2
echo "a1 = " $a1
echo "a2 = " $a2
It doesn't wait for input at "read a2" and a2 doesn't get set. Is the
"Enter"
key being read as a <CR/NL> pair? Is there a fix?
Thanks,
Tony Richardson
