Wow. I still don't understand why modify_bg would be that slow, but at least I can work around it, so thank you.

But now I have another question. If I move the pointer around with no buttons pressed, the cells change color every time it enters a new cell. But if I press any button and move the pointer while keeping it pressed, then nothing happens any more. Only when I release the button the cell where the pointer is at that moment is activated. In other words, it seems that pressing buttons inhibits the generation of enter_notify events. I've tried also with pointer_motion events, but it does exactly the same thing (except it doesn't activate the cell even when I release the button). I want the program to behave in the same way whether buttons are pressed or not. How can I do that?

Thanks again.
