Andreas,
thanks so much for this clue.
I have found that if I reduced the time in seconds from 0.1 to 0.01 to
0.001 to 0.0001 I only had problems with freezing on the 0.0001 time.
I tested on Win7(64 bit) on an Intel core i7 870 at 2.93GHz (16GB ram)(8
cores)
and a WinXP (32bit) Pentium 4 3.01GHz (2GB ram) using
R-2.15.2(2012-10-26) on both.
I had previously found that the tkgrab.set command seemed to be the one
actually freezing
so I placed the sleep command just before that with the same result as
it being just after the tktoplevel command.
I am now going to try it in my packages affylmGUI and limmaGUI, probably
with a sleep time of 0.1 to be on the safe side,
many thanks,
Keith Satterley

Maybe this will help to identify the problem (I have similar problems with
other tcltk-windows, too.)
Inserting some time delay after tktoplevel helps (on my PC):
test2GUI <- function(){
require(tcltk)
MainWindow <- tktoplevel()
Sys.sleep(0.1)
topMenu <- tkmenu(MainWindow)
tkconfigure(MainWindow,menu=topMenu)
tkgrab.set(MainWindow)
tkfocus(MainWindow)
}
Cheers
