R: R: R: R: Urgent please

Thanks, really appreciated.
So if i haven't understand bad, i can't use ambulant, since i'm using 4
channels PNG, right?
In one hand i have to handle transparency with png images, in the other one
i need to have a decent timing group management.
Right now i just can't get both, right?

I'm doing single .smil pages that href each others, to simplify the grouping
code and to let realplayer to crash less. It apparently do the job, but if
you leave the player open for a bit, and you then keep using the
presentation, then it will create some bug with image or text.

If i could handle the graphic image i created with ambulant would be
perfect, but i had no success on that

It's not essential.

The file I sent is correct and does what you intended it to do (as far as I
understand your intentions).  However, the RealPlayer obviously has some
bugs in the excl department.  It really is supposed to clear those images
before fading in the next set when you click on the arrows.  When I try the
example in Ambulant or GRiNS (with .png changed to .jpg) it works correctly
(modulo the transparent bits in the images).

I believe that the example you give here also shows the bug in RealPlayer.
It is indeed essentially the same as the earlier example.

You can report the bug to Real.
