Bug report for cygwin X server (or xterm)

xterm*VT100.Translations only when mouse is over the window with focus

Discovered with click-to-focus, in FVWM

In particular, I'm talking about the function keys. In this case, these
are NOT mapped in fvwm, but in xterm.

Pressing a function key, like F1, always writes to the window with
focus, but only performs the X11/xterm translations when the mouse is
hovering over the window with focus.

So, I always have to move the mouse to the window to be able to write to
the window. Otherwise, \e[P is written to the window, for example

Note that I can visit various windows with keyboard shortcuts, so
there's no natural correspondence with mouse position and window focus.

This failure to do the X11/xterm translation only occurs with x11/cygwin
xterms. Windows opened locally via sshd (port forwarded) behave
normally, performing the translation to the focused window, no matter
where the mouse is.

This last point leads me to the conclusion that this is perhaps a
porting problem of the xterm virtual terminal program, because when
xterm is executing on another machine, it doesn't happen.
