R help - Nov 2011 - tcltk window freezes when using locator( )

Hello useRs
 
Using the following code:
 
library(tcltk)
win<-tktoplevel()
ff<-function(){
         plot(1:10,1:10)
         pol<-locator(1)
         print(pol)
         }
button<-tkbutton(win,text="test",command=ff)
tkpack(button)
 
makes the win panel stop responding when the plot is closed before choosing a
location. Usually, the windows task manager
has to be used to close the window (which causes R to be stopped as well) or a
message saying that R is not responding is
displayed. I was having the same problem with R 2.13.0 so I upgraded to 2.14.0
but the problem persists. I am using windows 7.
 
> sessionInfo()
R version 2.14.0 (2011-10-31)
Platform: x86_64-pc-mingw32/x64 (64-bit)
locale:
[1] LC_COLLATE=French_Canada.1252  LC_CTYPE=French_Canada.1252   
[3] LC_MONETARY=French_Canada.1252 LC_NUMERIC=C                  
[5] LC_TIME=French_Canada.1252    
attached base packages:
[1] tcltk     stats     graphics  grDevices utils     datasets  methods   base  
 
Am I doing something wrong or more likely is this a bug?
 
Thanks,
Francois Rousseu

In fact, the same thing happens (window freezes) when a long computation
generated by the tcltk window is stopped through the R console.
 
library(tcltk)
library(svMisc)
win<-tktoplevel()
n<-10000
ff<-function(){
         for(i in 1:n){progress(i,n)}
         }
button<-tkbutton(win,text="test",command=ff)
tkpack(button)
