Sure it may be platform dependent.

I cannot prove it without seeing your code, but I don't think so.

The -pady values (without suffixes) are in pixels. The symptoms you describe (1 too small; 2 too big), are indicative that the y padding is being added both above and below. And that is indicative that the button is being packed with the default -anchor value which is centre.

You should find that if you adjust the packing so that it is no longer centered, the -pady will only be added to one edge, allowing you to match it to the Optionmenu size with -pady =>1.

By the way what is this 'map' thing?
