When adding a Google Gadget that includes preferences as an external gadget, adding the gadget works, but the edit screen remains hidden, and thus it's not possible to enter preferences or cancel out of the edit. Steps to reproduce:

1. Add an external gadget to your Studio instance, such as one of the following
   #*http://www.google.com/ig/modules/tabnews.xml
   #*http://hosting.gmodules.com/ig/gadgets/file/112581010116074801021/hamster.xml
2. Add the gadget to a dashboard
3. Attempt to edit the Gadget preferences
4. The gadget will resize, but the controls will not be displayed.

Customers can work around the problem by adding the following to a user stylesheet that's applied to content loaded from their hostname.

.dashboard-item-content .hidden, .dashboard-item-content li.hidden { visibility: visible !important }

The method of applying the workaround is unfortunately browser-specific. Here are some tools and tips that can help with common browsers:

• User Stylesheets in Internet Explorer
• Stylish for Chrome
• Stylish for Firefox
• Safari: Use the "Style Sheet" option in the "Advanced" section of the preferences panel.
