Can't take a screenshot when Software installation options menu is opened—is it a bug?

[deltastarshine (Regan Parks)]

When I click on the button to open the menu (pointed by my cursor) and then press PrtScr to take a screenshot nothing happens.

Is it a bug or a standard behavior where another key is used for screenshoting?

Mh. Works for me.

As you can see I took a screenshot.
