This is the last time I'm asking this, yet agian, sorry

The answer doesn't change :)

Native look and feel means it looks different on each platform, even if by mistake

Is the platform showing the diamond instead of circle for radiobutton using the latest perl/Tk? Tk-804.029_500 ?

If the answer is yes, there is nothing you can do :)

Tk::Radiobutton just doesn't let you choose what kind of indicator, circle or diamond

You could try setting tkvars$Tk::strictMotif, but I doubt it would help

short of implementing your own widgets, say, using Tk::Canvas, Tk::ImageButton..., there is nothing you can do

If you upgrading Tcl/Tk and switching to Tcl::pTk, maybe it allows you to change Styles and Themes, maybe using tile ...

Prima on the other hand should look the same on all platforms
