tcltk freezing using MS Windows for R-2.14+

R Version 2.15.0/Windows XP

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
Andreas
