Function Ctrl+0

[dindo]

Hello,
if, after starting to work on the image, I bring this to a 100% magnification with the key combination Ctr + Alt + 0 and then, wanting to go back to a total visualization of the image, I enter the command Ctrl + 0, the program it crashes and closes.
I also find it quite illogical that if you select the dropper tool and are in 100% view, you can not move around on the photo using the spacebar keyboard shortcut.
