iOS Question Crash after page resize

This is my first B4i app, so bear with me...

My app is crashing on startup and I get this on the log:

Application_Start
Application_Active
When page_resize event raised : 13:32:04
SignalHandler 6
Error occurred on line: 360 (Main)
Signal - 6

Line 360 is the end of the page resize Sub:

358 Private Sub Page1_Resize(Width As Int, Height As Int)
359 Log("When page_resize event raised : " & DateTime.Time(DateTime.Now))
360 End Sub

Why is this happening ?
