[Qt-creator] Does not show collapsed text

[Карелин Павел]

Hi, guys

I use QtC 4.7.1 I noticed that when move the cursor over the thumbnail 
"collapsed code", the text does not appear. See pict at attachment.
I wanted to ask: maybe in QtC 4.7 there was an option which is turning 
off automatic display of the collapse text? Or is it a bug?
