There’s one annoying problems with my Mac laptop. When I’m at work, I connect to external monitor and work on both built-in monitor on my laptop and the external monitor. When I go home I unplug the external monitor, close the lid and let the laptop goes to sleep. Once in a while, when I got back to work, I plug it in again and some of my running programs can’t be minimized anymore. I mean the yellow minimize button is grayed out or disabled. If I close the application and start it again, the minimize button appears again. However, having to close the applications and launched it again is such an inconvenient.
Here’s the screen shot of my minimize buttons when I have the problem.
I kept Googling and finally I found this post in a forum. So strangely enough, the problem is due to a bug in QuickTime. And sure enough, most of the time, I have QuickTime on anyway.
How to get back your minimize button without closing the window and reopening it.
Here’s the step:
- On QuickTime, open a new movie.
- Make the movie full screen. (You can do Apple-f or from the menu, click on View -> Enter Full Screen.
- Exit from full screen movie and close it.
- Now check your other windows. You should get your yellow minimize button back.
