Here’s another curious bug that I’ve just started experiencing (seems like I’m having one of those weeks!) Occasionally, the window cross icon on the top right seems to go rogue and start acting out another menu command. So every time I press it, it will zoom in on the canvas instead of closing the window, or create a comment, or (distressingly) save the file. These are the three that I’ve experienced so far. When  it happens, it’s consistent, so that every open window has the same problem, and I have to force-quit PD (probably I have to force quit because the console cross icon has also been affected). I haven’t spotted a trigger for this behaviour yet, it seems to be random. Has anyone ever experienced this? I’m on 0.47.1, Windows 10.
