That's deliberate, and mentioned in the rw-FAQ.
6.3 When using Rgui the output to the console seems to be delayed.
=================================================================
This is deliberate: the console output is buffered and re-written in
chunks to be less distracting. You can turn buffering off or on from
the Misc menu or the right-click menu: <Ctrl-W> toggles the setting.
If you are sourcing R code or writing from a function, there is another
option. A call to the R function `flush.console()' will write out the
buffer and so update the console.
You will normally see no output until there is an input prompt or
there is a Windows repaint event.
> It would be nice if this would be corrected in future release.
It's a feature!
