So far, no problem...

I'm not seeing this (vim 7.4.5, netrw v150f): ie. using <c-w>k to change
windows worked.

Doing this yields: E492: Not an editor command: 1yA .
Modifying it to
:let @a=''|windo norm! 1yA
yields
E21: Cannot make changes, 'modifiable' is off

because the netrw window ended up as the final window.

This command caused the cursor to move to the last line of both windows.

Yes -- may I suggest that you upgrade your netrw to the latest (v150f)
