aha. this sounds like might be the way to investigate. I know i have QT 
installed but not sure about the second machine. I am going to ask. thanks.

i know, i know... but i dont have the second machine with me. I also am 
fairly sure we had both same version when I did the tests 0.39-3 
extended with GEM 0.91-cvs compiled Dec 11 2006. Pretty old one...
So I thought this error might be more to do with some codec not being 
installed on the system, or some windows version issue. I am going to 
try to get more info on the second system.
