Yep, got that already :-)

That's what i'm afraid of.

3-4 years ago printf was vague, who knows what another 3 years can bring.

Of course, let the newbies do the dirty work..

Heheh, but my function is useless, anyone looking at VidMgr should see 
it's merits and capabilities, without too much explanation. 
Oh btw, i've found it. Serves me right putting it under libs\vidmgr\ :-)

I think it's the first time that anyone released a complete text video 
library AND source, most of the time they come in .libs, which
as far as i'm concerned leaves me without a chance to fix potential bugs
in them.
Bgiobj30 and a re-write of four weeks work comes to mind.:-(
                  
Ps: Sorry, had to cut a "small" part of your mssg. 
Got a bit dirty, while it was dragging on the floor !! ;-)
