Dear Wolfgang and Fabrice,
I am sorry. I didn’t notice that there is a difference between my code and Fabrice’s.
I made a wrong comment.
I know that there are several options in the animation module: menu, menustyle, menucolor, framerate.
Would you please explain the menustyle option once more?
Thank you so much.
Best regards,
Dalyoung
