closing figures with Ctrl+F4

closing a figure using Ctrl+F4 started pooping a 'save as' dialog, how do I stop this? (I started using R2016a)

I have this problem also and I haven't found a solution. It is extremely annoying.

I am also having this problem. Yes, it is extremely annoying.

In R2019a it appears to be somehow connected to the menu bar, and if I disable the menu bar, it suppresses the behavior.

This exhibits the problem:

f = figure;
imshow(ones(100));
(press Ctrl-F4)

This does not exhibit the problem:

f = figure('MenuBar', 'none');
imshow(ones(100));
(press Ctrl-F4)

Most of the time I can live without the menu bar, so this is an acceptable workaround.
