Flightaware Closing down in the middle of a session


#1

i had downloaded Flightaware app from Apple Store on my iPhone 3gs. Application works well the first few times i use it but then, it opens up and closes down while am using it and at other times, it seems to get stuck at the opening screen while opening up. Now am forced to open it up in a web browser with the mobile version. Any solution?
