Help - App Application time out

Is there a specific application time out for Mekorama?

I have noticed that when I'm going back and forth between the Mekorama application in one window and the Mekorama Forum in another window, that Upon returning to the mekorama window the application will restart and I will have to find which card I was looking at again.

I have a rather embarrassing number of cards that I have downloaded to my application and so having the application restart I'm trying to locate my last position is not always the ideal situation. I seem to spend a lot of time doing this so I was curious as to whether it was a feature of the application or a feature of my device.

If I post to send the wrong forum please feel free to direct me to the correct location as my feelings are not easily hurt.
