[R-gui] further on the Rcmdr package

[Philippe Grosjean]

I am away in a symposium, so, I could not check your issues myself. However, I also experience the problem of Tcl/Tk dialog boxes appearing behind RGui. Apparently, RGui and Tcl run in separate processes and Windows consider they are two unrelated applications.

I would like to support your various dialog boxes in SciViews. It will require very minor adjustments, and you will got a MDI with better behaviour of TclTk dialog boxes under Windows.

Best,

Philippe Grosjean

>Dirk's suggestion, I've added an option to Rcmdr to call tkwait until the 
>Commander window is closed. Apparently this solves the problem that Dirk
