If this is a fast non-interactive command, then execute it like:

  PipeRead `xterm +sb -geometry 50X30+502+310 -e .fvwm/updatePager >/dev/null`

(do you really need xterm here, maybe "Exec $[FVWM_USERDIR]/updatePager"?)

If this is long or interactive command, then do this:

  DestroyFunc updatePager
  AddToFunc updatePager
  + I Exec xterm -e .fvwm/updatePager; xmessage -g +2000+2000 -class "DummyWindow" ""
  + I Wait DummyWindow
  + I Read .FvwmForm-Pager

Or use the method suggested by Dan.

Mikhael.
