The overlay is expecting a fixed widget because your width and height are set to None.What you are trying to do will probably work in a future release of Urwid, I just haven't gotten around to implementing the ability for Text to behave like a fixed widget yet. I guess I should get to work on that! :-)You need to:1. set a value for width and height in your Overlay, so that it expects a box widget2. wrap your Text widget in a Filler widget, which is a box widget.This means that it won't intelligently resize based on your text for now, but that's the best option I can see at the moment.Ian
