Hi Andrew,
I can see that with your patch the application now doesn't
hang anymore when highlighting and/or clicking on buttons.
GUI performance of applications on my embbeded
system seems also to be quite better now.
I wonder if there's still some place for UI performance
improvement.
Thank you,
Francesco
