How to remove Enhanced Splash Widget from an app in Flex Builder 3.4

This may sound like a dumb question but here is what is happening:

I am using this tool with Flex Builder 3.4. I have more than one applications. I installed this tool for 2 of my applications (app A and app B) by adding the line into each application's main config file and than copying and pasting the compiled version of the mysplash widget folder into each application's widgets folder. It works great.

HOWEVER, when I wanted to remove this mysplash widget from one of those two applications (from app B) by deleting the <splashpage url="widgets/mySplash/SplashWidget.swf" label="ArcGIS Viewer for Flex" config="widgets/mySplash/SplashWidget.xml"/> line from the application B's main config file and then deleting the mysplash folder from the application B's widgets folder, for some reason, every time I make any changes (unrelated to mysplash widget) to the application B in the Flex Builder and save the changes, Flex builder automatically adds the <splashpage url="widgets/mySplash/SplashWidget.swf" label="ArcGIS Viewer for Flex" config="widgets/mySplash/SplashWidget.xml"/> line back into the app B's main config file causing the application to show an error message at start up since the mysplash folder is no longer in app B's widgets folder.

Can someone help me understand why this is happening and how can I stop the mysplash coming back to my application B's main config file every time I make a change in the Flex Builder for app B please?

Thank you,
