Not able to click anything after I select one thing
This is my first time using this program so this might be a lack of knowledge. But when I launch Gimp I can select one thing for example text size but after that I can't unselect it. I tried the ctrl+shift+A tip I saw online but that didn't work and also I tried to restart my computer also didn't work. I can't select other tool, the close red X on the top right corner, anything. If you could help me with my problem that be much appreciated.
