There are some days ago, I had a problem with my Sublime Text 2. Indeed, I can write the SAME things several times, it doesn't work. I delete (one more time) my line of code (to be exact, it's a css class), write again, and by magic it does work.
I worked on a HTML/CSS page. I make the same things on my portable computer and it work well, I would like to understand why I have this problem. One more thing, I make a clean install 5 days ago.
Sublime Text 2 v2.0.1 with the following installed packages : Sublime Package Control / ZenCoding / LiveReload
PS : I hope you understand what I say.
