I appear to have found a problem with iOS7 Safari on iPhones when turning the screen from landscape to portrait.
Link to .capx file (required!):
(This file is the most basic case, window size and layout set to 640, 744 with one sprite filling the screen. Fullscreen in browser set to Letterbox scale.)
Steps to reproduce:
1. Load game on iOS7 iPhone (4S and 5 tested)with phone portrait
2. Turn phone to landscape orientation
3. Turn phone back to portrait orientation
After turning the phone back to portrait, the game reappears half off the screen.
Game not to be half off the screen!

Construct 2 version:
First found the problem with r156, I then saw the new stable release r158 was available so I upgraded to that version but I get exactly the same problem.
I then downgraded to r154 which I knew worked with some older projects I'd worked on and it work as expected.
The problem seems to have been introduced between r154 and r156, I didn't try r155 so I don't know if that one is affected.
