gnome-do window pops back up if I finish my action too fast

If I finish my gnome-do action too fast, the gnome-do window re-shows after I hit enter, ie something like this:

*) I invoke the gnome-do window
*) I type "efo" which makes gnome-do recognize firefox and I hit enter
*) gnome-do window goes away
*) gnome-do reappears ready for input
*) firefox starts in the background
*) I have hit esc to get gnome-do away so I can use firefox

If I give it some time before I perform an action, there is no reappearance of the gnome window. Which ofcourse is annoying. The whole idea is to do things instantly.
