I am the maintainer of oneChannelGUI. I am observing a strange behavior 
of pop-up windows generated by my package and by affylmGUI.
For example if I execute the set working directory command under 
affylmGUI from affylmGUI menu or by as line command: SetWD()
and I repeat it 10 times I get at least ones that the pop-up window 
freezes and I cannot delete it or writing in it, unless I maximize the 
pop-up window and then I can see, in the upper-left corner of the 
screen, the regular window and I can interact with it. It seems like 
that tcl window every sometimes opens up not in the right screen 
coordinates and, unless you visualize it on full screen, you are unable 
to interact with it.
This is quite erratic but frequent event, not only for the SetWD() 
function but in general for tcl windows in affylmGUI and oneChannelGUI. 
I tried to see if something like this happen also in the example of 
tkWidgets but I could not obtain the behavior I observed in the above 
mentioned packages.

I have observed this criticality only in windows 7 and never in linux.
This suggests me tha tthe problem might be linked to the tcl/tk 
libraries embedded R windows installation.
I would like to see if the problems I am observing are also present in 
case an external version of tcl/tk libs is used. There is any command to 
force R to use external tcl/tk, e.g. and installation of active tcl/tk?

Any suggestion to solve the problem I encountered is very welcome, since 
the use of the interface is getting very boring if you need to maximize 
pop-up every sometime.


  P.S. I observed the problem on a locally compiled version of R under 
windows and also downloading the latest R 2.14.1 for windows
