iOS Question B4i Ver1.8 Bug?

Where do you use it ?
The current screen size is known in the Page1_Resize routine not in Application_Start.

i kind of use it everywhere. I found a weird work around of resizing an image in designer script and then using the image height in my code. and then using math to figure out percent that works.
its definitely a bug. designer script 100%y works fine.

100%x and 100%y are only guaranteed to be correct inside Page_Resize event.
