Hello, seems that you’re setting the window content size to full. This means that the content is always 100% wide and 100% high compared to the browser window which effectively disables scrolling. As Window extends Panel it’s by default scrollable if the content of the Window is higher than the window it self. Your problem is that you’re making the size of the content to match the size of the window.
