After downloading the app in my mobile when i open it first screen is properly working but second screen keeps on repeating continuously when i press back button continuously it works properly. can u plz tell me how to fix this problem

As suspected you use a clock. Use this blocks in Screen1 [image] Also notice how I changed the procedure for closing screen, you should use it like this in all 15 screens cause otherwise memory errors might arrise. Also 15 screens are too many you could always work with "virtual" screens.

Do you use a clock that forgot to set it to false ? Do you close screen correctly? Please post some screenshots or post aia
