buttons desappear when i set the size of the alert window

Good morning all,

My question of the day :

My project works fine (onclick-button name or ID ), but now i would like to set the height of the alert window containing my set of buttons.

i set the window location at the top of the screen like this:

win.frameLocation = [800,0];

then my buttons are created dynamically (the number of buttons can change)

i set the size of the window for exemple with:

win.size = [1024, 50];

but the buttons desappear ...

i tried to place the code before or after the button creation , but it doesn't work...

well.. before i dive in a "no ending" exploration due to my poor knowledge in js , could you give me a track or a direction to explore ...

Thank you !

the code:
