Possible Solution for Resume Saved State on HTML5 Output
We recently ran into the issue when viewing HTML5 output on Mobile Safari...the one when a screen doesn't appear to listen to its "resume saved state" property.
We discovered the screen is actually not 'restarting.' It just doesn't show pictures (e.g., a hidden picture that's triggered to appear normal...such as a checkmark on a menu item). HOWEVER, text boxes DO work! They appear when revisiting a screen as you would expect if it's set to resume the saved state.
(Note that you can use Wing Dings or other fonts to still have picture-like items.)
Hope this helps anyone running into the same issue.
