Hi! Someday it's occured that i cant make a right click to Firefox on a Windows start panel - when i use right click the windows just... disappeares. What can i do to solve this problem? Check the screens The correct work of right click on the panel is shown on the screen "correct work" It works with all the apps, but a month ago i noticed that when i make a right click on Firefox on my start panel nothing happens, it just disapeares.
