I have been having this problem with my Anki the past few weeks. I am unable to close my Anki window. The window is stuck as seen in the image attached. I am unable to access any part of the menu. Pressing the ‘X’ does nothing. I have restarted my computer. I have even uninstalled the program, and this window is remaining on my screen. If anyone has any advice, please, I would love to hear it.
