Change Cursor to another window on BufWritePost in Vim

I have a function that whenever it is called it splits the window and displays some information, placing the cursor in this new window.

So far so good.

But I am implementing an autocommand that will trigger the same function, and everything works great except that the cursor never changes to the opened window like when it is not running with the autocommand.

The line that triggers this looks like:

 autocmd! BufWritePost *.py call MyFunction()

Like I said, it works great when you call manually :call MyFunction() but not with the autocommand.

I think Bram mentioned that autocommands are really not meant to split windows or even move the cursor.

Is there any way around this or am I doing something wrong?

Going by what ZyX said in the comments to original question, it sounds like this would work:

function MyFunction()
    [ have all commands you currently have]
    [ . . . ]

    " then as last line include call to feedkeys()
    " this will stuff keystrokes into key buffer
    " and get executed after MyFunction() ends
    " remember that location will always be in 
    " original window, i.e, window that vim
    " was in when autocommand was triggered
    " so if new window is below original
    " window you could use this:

    " feedkeys call below edited to reflect ZyX's
    " improvement of \<C-\>\<C-n> to guarantee
    " we're in Normal mode before using window
    " movement key combo

    call feedkeys("\<C-\>\<C-n>\<c-w>j", 'n')

endfunction
