Sometimes if I don't like the way something is laid out I make a duplicate of the page and then tweak it to however I want it. If i like it better, then I keep it. That usually means I delete the old page it was dupped from but now that doesn't work. I get the Red Screen of start up.
The Entry and the TextDisplay are not even used. Why can't I delete them?
Resolved:
In App Settings > App Details > Initial Page
It kept changing the Initial Page, it had pages in there that would not show anything without passing data. so of course it gave an error.
Is it supposed to do that, just automatically switch the Initial Page.
