I was just placing a slider and nothing seemed weird when all of a sudden it closed.
If it makes any difference, I was editing this map but there were like 5 notes in it at the time.
On a side note, what's with the square in front of the titles in the now playing section?

Edit: Same thing happened again, I think it has something to do with adjusting the curves of sliders.

p.s. how much video memory do you have

Same Problem.

Fixed in latest test (only affected test in the first place ).

I still have this problem. I get it while moving sliders.
