I don't see where you answered the person that tried to help you in your other thread. Did you miss his posting today?
The default text based editor for most UNIX/Linux systems is vi and vim is an enhanced version of that. You talk about "gvim" which is the GUI version of vim. It wasn't clear in your other thread if you had tried that or not. It also wasn't clear why you were upgrading the gvim in the first place.
I'd suggest continuing to work on vim by going back to your original post and responding to today's post.
There are of course other editors such as nano and emacs for Linux but only apostates use them.
Also you says "for windows" in your post. Since you were talking about RHEL5 in your other post I'm assuming you mean X Windows rather than MS-Windows but on the off chance you meant the latter note there is a Gvim available for MS-Windows and it works because I used it.
