I would like to know of anyone else is experiencing this.

I am trying to create a new tab builder template using/modifying an existing one.

When I am modifying it in the tab builder editor, I can do just one change and when I

go to save it the window that says tab builder is not responding comes up and exits.

This has happened every time.  I am doing this at home using SW 2011 SP3.0 on Windows 7 64 bit.

Does anyone know if this is a known bug?
