Syntax highlighting for classes, input variables etc. does work for most of the files in my solution, but there is one cpp-file that it doesn't. When you open the file you see that it highlights, but only for a millisecond, and then it disappaears again.
Highlighting for words like if, while, return, true, false works fine. I use Visual C++. All other solutions and files that I work with works great. It doesn't mather if I close the file and opens it again, or restart the computer or so, it's just this file that don't work.
