Edit 2:  Apparently the gadget did update, but recent changes to Gallery means that the new code was uploaded to a different URL than the old.  You'll have to go back to Gallery (link below), click "Add to my space" again, and remove the old one.  The gamertag configuration you set with the old code will continue to work with the new.

Edit:  Well, Gallery accepte my submission but didn't prop my new code, so version 1.4 on the Gallery doesn't have the updates below.  I'm following up on this to see if I can get the update fixed, and may have to resubmit the gadget.

The next update to my Favorite Xbox 360 Games gadget should be uploaded on Gallery soon.  You'll know it's there when the version number is 1.4.  Here's a sneak preview:

Can you spot the differences?  (Ignore the broken images.  Xbox.com was down while I was working on this, so game tiles failed to load.)

1. Rounded corners.  This makes the gadget look a bit better on dark-themed Spaces.  Technique "borrowed" from Alessandro Fulciniti's Nifty Corners Cube technique (the Nifty code was not used, just the idea).  If you use a white background on your Space, the corners are essentially invisible, but they're still there.
2. Icons!  FamFamFam's lovely Silk icon set makes another appearance in one of my gadgets (previously used in my Similar Artists gadget).  This time, the wrench replaces the old "Edit" text and the refresh arrows are added for ...
3. Refresh functionality.  Not all that useful, since 360Voice only updates once a day, but the functionality is there and may be useful if the gadget fails to retrieve data for some reason.  Edit will still only be available to Live.com users and while in Author mode on Spaces.  Refresh will be available to all users at all times.
