Build ID: 2000042113 When entering text into the text entry portion of a form, pressing space causes the page to scroll (if there is page left to scroll). This seems to 'come and go' ie. this does not seem to occur all the time. Suspect that under certain circumstances (will try and figure out what those are) mozilla does not realise that it is in 'form' mode and still maintains the page scrolling effect of using the space bar.
