[momar33]

When i have more than one child an i click on the child that is not in front, it does not change focus to the child in back unless i click the title bar.

Here is my code:

expandcollapse popup

I quite have the same problem!

I wanted to make lo3n's Script embedded on the Desktop and put some custom controls to them.

But when i make the GUI to a Child of the Desktop, the buttons and labels hide behind the background and dont come back.

I tried a lot with Styles but nothing seems to work. There has to be a soultion.
