This has been driving me crazy, especially because I feel like I should
know the answer....
I have IDEA 6.0.4 installed on a Windows machine at work and on a Mac at
home. The configurations aren't identical, but they're close. I use
Perforce in both environments. On my Mac at home, the right gutter
contains markers that indicate differences between a file being edited
and the version that was checked out from Perforce. Those markers don't
appear on my work machine, and I can't seem to find where this behavior
is configured. Can someone point me to the right place? This is a handy
feature that I'd like to turn on on my Windows machine.
