I hadn't looked closely at the code Pablo.  Maybe we could do that for
the next time you do this?

Well I did delete it afterwards, but I could always compile it again.
Only you can tell me if it works as you expect it to.  Better we take
this discussion off-list and I send you a link though.

Well unless your hardware is doing something weird, or you yourself are,
on the compile, then I'm not sure what could the issue could be.

I downloaded everything as is from the links you posted.  Everything that
is, except the font - I used FreeSans.ttf instead.  Compiled, and off it
went..

I was, as you guessed, pulling a leg or two there, but, sure you can! ;o)
My laptop is a bit of a mash-up, with a few different things on different 
partitions.  The main partition started life with a minimal install of
Vector Linux ( a light Slackware derivative ).  All else, including a
kernel / libc upgrade, along with several versions of SWFTools, is from
source code compiles.  I'm not sure exactly what it is now. I must like
pain though, huh? ;o)

Again, I didn't look closely at your code to see what they were supposed
to do. But, they didn't appear to do much.  UP and DOWN seemd ok. The
others..?

Your choice entirely.

I *was* pulling your leg again there, Pablo! But, why not?  Music quietens
the savage beast or similar.

You can be as way too serious, as I can be silly. It sounded fine. ;o)

Hey, we agree! ;o)

Sort of.  I humbly submit he needs to use more ups and down in vocal
pitch, and/or punch the points he makes with the right choices. Same
goes for the silences or lack of them, for emphasis. That and learn
how to breathe. Tough critic aren't I? ;o)  ( I'm not sure I could
do it any better myself.. )

Unless there are any salient points to be posted here, I will
off-list you.

Chris.
