scribe for Mac steals window

[swmuruga]

on Mac OSX (10.4.11) using Express scribe 4.05 I find when writing a file in Word that when i need to stop or start (using keyboard shortcuts) I must put cursor in the scribe window to make these functions active - this is quite dfifferent from what i have done in Windows XP where I can type and use keyborard short-cuts with scribe in background. any help would be most appreciated.

thanks
