I've recently switched over to using VIM and use a friends .vimrc that works well for him
I first installed vim through Homebrew as well as symlinking MacVim. Everything seems to work well except in a few files in my project. One .scss file freezes VIM everytime, most of the times upon trying to open it from NerdTree, but sometimes just navigating within the file. When this happens I have to completely close my Terminal tab, as well as force quit a VIM process in my Activity Monitor that goes to 100%.
I've tried many things to fix the problem such as uninstalling VIM/MacVim via Homebrew and downloading MacVim from MacPorts and symlinking it manually. I have also tried other .vimrc files and still have the same problem. I feel as if I potentially installed a bad plugin previously and it or something related is still cached somewhere on my machine.
The only time the problem does not occur is when using the VIM 7.3 compiled by Apple that shipped with my machine. Any information on debugging this problem would be greatly appreciated
