Please ignore this message, because it's a windows 95 problem. All our
windows 95 PC's on our intranet have this problem.
The PC-hangup is not only when you transfert that image over the network.
Even if you want copy the file or do something else with that image on your
PC, will hang-up de PC for a couple of seconds.
I'm terrible sorry to bother you all.
Sean,
I've changed the images in the header-files in plain text.
