Today I Installed Visual Studio 2010 on Windows 8 beside Visual Studio 2012, and what I noticed is that the active file - the one I am editing now - is not highlighted in the Solution Explorer, and this was really annoying as moving between files dose not showing me which file in the solution hierarchicy I am editing. And I though it is a bug in the beginning but I figured out that it is an option:
From "Tools" go to "Options" then "Projects and Solutions", and under "General" change"Track active item in Solution Explorer" to checked.
I don't know why there is an option like this, why a user may need to edit a file and that file is not highlighted in the solution explorer
