[R-gui] Something odd about Windows GUI with the menu command

[Philippe Grosjean]

Hello,
This is not a question for R-SIG-GUI (Graphical User Interface), isn't 
it? You may get answer, or not. If not, I suggest you redirect this 
question to R-Help, or directly submit a bug report if you think this is 
a bug (but you should first try this with the latest R 2.6.1).
Best,

Philippe Grosjean
