I'm using VS2008 (version 9.0.30729.1 SP) and have found that outlining regularly stops working. I get outlining options for the start and end of functions, and for comment blocks, but not for other code blocks, such as ifs, while loops, for loops, etc... Using Reset all settings, as recommended in a similar previous question temporarily fixes the problem, but it comes back going in and out of visual studio. It also has the side effect of requiring me to reset all my C++ directories. Any ideas how to resolve this?
Edit: Using Right Click / Outlining / Collapse block works, but is a bit tedious. I'd really like to see the embedded pluss and minus symbols on the graphic outline. I've tried all the other outlining sub-menu options but to no avail.
