Hi Christian, The file with the problem is _vimrc itself, which is how I noticed it.
Here is a line from my _vimrc that shows the problem: :hi Tab ctermbg=235\t" Grey19 = 0x303030 The \t is really a single tab character. My assumption that _vimrc is an "rc" file appears to be wrong, because if I copy _vimrc to xxx.rc, then xxx.rc does not have the problem.
