R help - Feb 2011 - R Tcl/Tk [MacOSX] TkButton Problem

Hi,

I have a tktoplevel window and in it a tkbutton:

AUS <- function()
{
	foo(parameters);
}
AUSButton.but <- tkbutton(tt,text="OK",command=AUS)

The function foo(...) does a time-consuming calculation, and during this
calculation there is printed some progress information to the console.

My problem: When I click the button "OK", the tktoplevel window and
the R console don't react anymore, and there is nothing printed to the
console until the calculation is finished (then all informations are printed out
in one step).
If I simply execute foo(...) in the console, the progress information is printed
out step by step, as I want.

Is there a possibility to change the call of foo(...) in this way that R and the
window don't stop responding?

Thank you!

The flush.console() function will cause R to display pending text if 
you're running in the GUI.
