Strange vi/vim issue on cmd+tab switching

I'm having the following issue. Macbook Pro running Windows 7 as guest OS:

1. Open Putty and SSH into a Linux machine
2. Open vi (or vim)
3. Cmd+tab back to Mac OS
4. Cmd+tab back to Windows guest OS
5. Now to vi help page is suddenly displayed

Normally the vi help page is invoked by pressing F1. I haven't found any Parallels setting to influence this behaviour yet. Any clues?

Edit your .vimrc in your home directory on the Linux box and add a line that reads:
nmap <F1> <nop>
That will fix it.

 

No, it doesn't fix at all ..
Its so annoying !!! Not in Parallel 13
Does somebody have any idea?

 

Add the following to your .vimrc file to fix this.
:noremap <F1> <nop>
:noremap! <F1> <nop>

 

Add the following to your .vimrc file to fix this.
:noremap <F1> <nop>
:noremap! <F1> <nop>
