NSB App Studio v18.104.22.168
Safari on iPhone 5 and iPad Mini
Windows 10 PC Chrome
The issue is that depending upon which setting of Screen Mode is used, the results vary as a function of ScreenMode... some results as documented, and some an ugly surprise... Such as screen turning all black (white controls are displayed correctly... Such as form location starting half way down screen... Such as zoom results in oversized in vertical, but okay in horizontal direction.
The program consists of only the following... a button at the top of the screen and a button at the bottom of the screen... no code.
Properties are as follows:
Background color black
DefaultForm Size iPhone 5
ScreenMode Full Screen On PC (Windows Chrome) all colors correct, form located in upper left
....On iPhone, okay
...On iPad, all colors correct, but form located upper left (I wish it would fill the iPad screen)
ScreenMode Actual Size on PC, screen is totally black and white controls
...on iPhone, screen is totally black and white controls
...on iPad, screen is totally black and white controls and form located upper left
ScreenMode Centered on PC, screen is totally black and white controls, form is centered horizontally but top of form is about half way down screen
...on iPhone, same as on PC
...on iPad, same as on PC
ScreenMode Zoom... screen totally black but controls white.. form doubled in size, but top of form is about half way down screen.
...on iPhone, screen totall black but controls white... fills screen as it should
...on iPad, All black except controls... fllls screen horizontally but vertical is oversized (but scroll works to show hidden part of form)
