If the window is already opened, then the user will still be clicking on
the link and the secondary window will not be brought up on top. This is
a very frequent and major usability problem with secondary window and
your code does not address this issue.

The popup will be non-resizable and will not render scrollbar(s) if
content overflows requested window dimensions; in both cases, this is
not user friendly and is not usable.
Also, if javascript is disabled, then the link will not be loaded in the
"bob" secondary window. Your code creates 2 sorts of behavior depending
on javascript support enabled/disabled.
