I find that the “help/informaion” popup disappear easily.
If you hover over an object with the mouse curser, and the popup shows and you just move your mouse a tiny bit the window will disappear.
In order for it to reappear you need to move the curser from the icon and back on the icon again.
can you please look in to if you can make this function as in most other programs or games.
Where the popup shows as long as you hold the curser inside the icon frames.
