For Mini 9 users that are having a hard time with windows that cannot be resized, such as WindowBlinds, you can try the steps below to get to the areas of the window you need access to.
-Make sure the window you need has focus.
-Press Alt+spacebar at the same time (a little menu will pop out)
-Press the 'M' key.
-You can now use your arrow keys to move the window around
-Press enter to place the window
If you go too far off of the top of the screen the window will snap back a bit.
