title: Magento Custom Module Admin Permissions
body: <p>I have created a few custom modules for Magento and when I try to assign permissions to the module (check the checkbox) when I click save it unchecks the box.</p>
  
  <p>Anyone have any ideas? It sort of sounds like there is something off in my config.xml file so I will post it here just in case:</p>
  
  <pre><code>&lt;config&gt;
  &lt;modules&gt;
      &lt;Wpe_Vendorlist&gt;
          &lt;version&gt;0.1.0&lt;/version&gt;
      &lt;/Wpe_Vendorlist&gt;
  &lt;/modules&gt;
  &lt;admin&gt;
      &lt;routers&gt;
          &lt;vendorlist&gt;
              &lt;use&gt;admin&lt;/use&gt;
              &lt;args&gt;
                  &lt;module&gt;Wpe_Vendorlist&lt;/module&gt;
                  &lt;frontName&gt;vendorlist&lt;/frontName&gt;
              &lt;/args&gt;
          &lt;/vendorlist&gt;
      &lt;/routers&gt;
  &lt;/admin&gt;
  &lt;adminhtml&gt;
      &lt;menu&gt;

                  &lt;items module="vendorlist"&gt;
                      &lt;title&gt;SO Vendor List&lt;/title&gt;
