Menu font is inherited from Windows - This is system wide. When you change appearance settings for menu fonts the menu fonts in your application will also change
I suggest you develop a custom solution for this.
Thank you for your answer.
Its disappointing, but not unexpected. Advanced Menu object doesn't have such option(but have several others regarding menu bar) So Im unsure ehenever an extension could be developed to change menu bar font.
At any rate, that answers my question, thread can be closed.
