I am using MacVim to write code in C++. I went to modify my vimrc file and accidentally clicked :w when in the file. After doing this, all the text seemed to disappear. After a while, I realized the text was still there, it just wasn't visible because for some odd reason it now was the exact same color as the background color (even though I didn't change anything). When I try to make a new file, the same thing occurs, I can't see the text (it seems to blend in with the background). I am not sure how to fix this, any ideas?
