First, excellent release on the web part.  Pretty flexible and easy to use.

I do have one issue though...

I have given users the ability to hide the Stock Quote web part.  After the user hides and saves the modified web part in his or her personalized view it disappears.  But after a refresh or navigating to a different page and back the web part re-appears as if the personalized settings are not saved.  Have any of you run into this before and know of a fix action?  The web part is already part of the GAC, so I know that is not the issue.

Any help would be great!

Thanks!
