VIM: Backspace deletes in normal mode, but does nothing in insert mode.

Preliminary Info:

Detailed Description:

When I'm in Insert mode, I can type text as normal, but backspace does nothing. While in normal mode, the backspace key deletes text. This is exactly opposite the behavior I had just earlier today. I have read numerous other posts online describing Vim's unorthodox backspace behavior, but the suggested config settings (namely bs=2 or bs=indent,eol,start) had done nothing.

More unusual is that gVim behaves "normally" that is: Backspace move the cursor to the left in normal mode, and deletes text in insert mode.

What I would like is for backspace to delete text in insert mode (just like most other programs) and to be navigation/disabled in normal mode. How can I regain this behavior?

Below is a copy of my _vimrc: (I would put this on github but my git is messed up at the moment and I've yet to fix it.) Additionally there was a function that was inside of the _vimrc by default. I have no idea what it does but omitted it to save space. If you want to see if I can post it in a reply.

source $VIMRUNTIME/vimrc_example.vim

source $VIMRUNTIME/mswin.vim

Most likely, your insert-mode backspace is mapped to do nothing (i.e. <nop>). Verify this by typing :verbose imap <bs>. This will show if backspace key is mapped and where the map was set.

What I would like is for backspace to delete text in insert mode (just like most other programs) and to be navigation/disabled in normal mode. How can I regain this behavior?

You can do:

iunmap <bs>
nnoremap <bs> <nop>

The first line unmaps <bs> in insert mode, thus <bs> will recover its default functionality. The second line maps <bs> in normal mode to do nothing.
