No, actually %system ...

If things do not work with standalone xanim, outside mgp, then
something's seriously wrong, either with xanim or your input file.
I don't know what to suggest here.

You need to have the mouse pointer over the animation, otherwise
the keystrokes will be caught by mgp.  But I guess you have tried
that.

Another thing that may be responsible for this is your window
manager.  My window manager is fvwm.  I have to tell it to keep
the xanim window on top of the mgp window, by giving it the command

Style "XAnim*"          NoTitle, NoHandles, BorderWidth 0, StaysOnTop

(this goes inside the ~/.fvwm2rc file.)  Other window managers will
have something equivalent.

Of course before doing any of these, you should make sure that 
xanim works properly as a standalone application, independently
of mgp.
