UiFlow 2.0 Firmware locks up my Core3

  • Hi, I have recently acquired a Core3 and have successfully installed UiFlow 2.0 firmware. There is a demo app in the main UI and you can select it to run once which it does and when you hit the reset button the Core3 reboots back to the main UI. You can also select it to run continuously and every time you hit reset the demo app restarts. Is there any way to return to the main UI once you have done this? Also, every time I upload a new app the Core3 runs it continuously and the original UiFlow is over written. I had assumed the new uploaded app would appear in the list of selectable apps with the main UiFlow program. Any guidance would be appreciated.
