sometimes when i am doing something that involves a dialog box, it will freeze and make it unable to close even if i end the corresponding application. i have found no other fix other than to force reboot, causing me to lose any data that I have.
attatched is a picture displaying the bug, the box in the middle unable to be closing even by using xkill.
i have possibly found a fix at the following url, but i cannot make any sense of it.
could someone help me? i am running cinnamon and linux mint olivia.
