Hello

I am developing a WRT app but I am facing a strange problem when I try to run the app on WRT 7.2.
While running, if the app is minimized due to any reason, the app is closed and a pop up saying "system error" is displayed. No error code is shown though. I have tested the app on Nokia c5-03 (WRT 1.1) and it works totally fine.
But this is not the case when i'm trying to run it on nokia c7 (WRT 7.2).Even if the app is left idle and the phone gets locked due to automatic keyguard, then on unlocking it..the same "system error" pops up and the app exits.
Can anyone tell me what is the reason behind this ?
Any response will be of great help
