Could you give us more info or even better the source code?  <br><br>Thanks,<br><br>- Matt<br><br><div class="gmail_quote">On Tue, Sep 15, 2009 at 8:15 PM, Alex Vollmer <span dir="ltr">&lt;<a href="mailto:alex.vollmer@gmail.com">alex.vollmer@gmail.com</a>&gt;</span> wrote:<br>

<br>

<br>
When I load the Nib in Interface Builder everything looks okay (no warnings or errors) so I&#39;m not sure what I need to change to make this go. Any thoughts?<br>
<br>
Cheers,<br>
