Nope, sorry, doesn't work :-(

I might have a fair number of little red dots on a couple of screens and I
would like to make them flash without having to go through a list using
fl_show_object. That's why I thought that, if I could change the palette, it
would be better.

Has anybody ever done something like this? I.e. remapping the X palette on
the fly?

Thanks
