*   Man this took a long time to fix. Simple little

*   app from crashing (hard) when you are running a
*   thead and you switch tabs.  You see the BTabView
*   detaches this view form the window then you select
*   a diffrent tab - thus causeing ALL output or input
*   from this view to die. It should probably not be 
*   this way, a BTabView should Hide() and Show() the
*   views it contains so that activity could continue 
*   while the user does something else.
