CQRLOG runs as expected on my Ubuntu laptop with Ubuntu 24.04. However, on my RPi 500 running RPi OS, CQRLOG starts with a small, gray rectangle/window on top of the logo - If I click the "x" to close that window, the program goes on to work as expected. If I "maximize" that little window, it just has CQRLOG in the top bar, and no other info. How to get rid of the little window on top of the Logo on RPi OS?
