Flashcard shortcut keys don't work properly

Almost every time when hit the space bar (shortcut: turn flashcard) the flashcard exercise gets closed. Is there a way to fix this problem, because I don’t want to use my mouse for every single flashcard (this way I have to change the batteries almost every day).

Edit: It seems to be only the first card and only if you choose 50 and more. So it`s only a minor problem, as - if I click the mouse button to turn the first flashcard - the shortcut works like before.
Maybe you’ll have a look at it, when you have the time.

@il_melomane70 - Sorry about that! I’ve passed this along to our development team and we’ll see what we can do to get this resolved.
