Having an issue with Storyboard and web views/tabbars. I can navigate from tab to tab and the view loads but then after leaving the view and coming back to a webview based tab bar it merges them and show both web views at the same time.

function scene:enterScene( event )

media.playEventSound( "Tock.caf" )

webView = native.newWebView( 0, 22, 320, 380 )
webView:request( "http://www.origintech.net/index.php")

-- "createScene" event is dispatched if scene's view does not exist
scene:addEventListener( "createScene", scene )
-- "enterScene" event is dispatched whenever scene transition has finished
scene:addEventListener( "enterScene", scene )
-- "exitScene" event is dispatched before next scene's transition begins
scene:addEventListener( "exitScene", scene )
-- "destroyScene" event is dispatched before view is unloaded, which can be
-- automatically unloaded in low memory situations, or explicitly via a call to
-- storyboard.purgeScene() or storyboard.removeScene().
scene:addEventListener( "destroyScene", scene )
