weird tab ghost image

Question

I've got a TabNavigator with multiple tabs. I have one tab that if I end the session on that tab, and I reload the application, then that tab appears -- instead of the default first tab, BUT elements of the default tab appear "ghosted" visibly on the last tab.

I've tried using

 tnAppDash.initialize();  
 tnAppDash.selectedIndex = 0;

but it still happens... any ideas?

Thanks in advance,

bw
