after press "PLAY", level selection pops, and when I click mouse, nothing happens and ESC or back button doesn't work. How can I solve this problem?

I saw the most recent update. I'm trying to track all these fixes so I can update my review accordingly. Now starting with day 1 launch, I could never get zoom to work, and apparently others had some ability to zoom. Whats my problem? I have tried on two different computers. It is 100% not a mouse issue (scroll works perfectly fine anywhere and everywhere else). I've tried the recommendation of using 'alt' or 'ctrl' keys, even though it tells you just to use scroll in the game. I'd really like to figure ...

There are two type of number lines, white and colour specific. What is the difference?

The screen gets streched so much its not possible to select the language and change the resolution later on.

It's mouse wheel, right? Thanks in advance,
