Update attribute dialog window when joins are removed

[PLadd]

When I remove a join from a feature class, the attribute table fields are refreshed to display only the fields in the feature class but the attribute dialog window should also refresh so that the joined fields no longer display in this window. 

The work-around for this is to remove the join, save and close the project, reopen the project, re-select the feature(s), and reopen the attribute window.

I see the behavior you're describing. My question, though, is that it seems you can clear the selection and re-select features and the joined fields no longer display in the Attributes pane (that is what I see). That doesn't work for you? You said that you have to close the project and re-open it, but I don't see that...
