I installed NERDTree via Pathogen on Mac OSX 10.6.8.
When I vim a dir, I cannot enter into sub dirs with enter key. Furthermore, the dirs look like this:
?~V? doc/
What's going on?
Putting this in my .vimrc solved the problem: let g:NERDTreeDirArrows=0
The creator gave me the fix: https://github.com/scrooloose/nerdtree/issues/108
