Vic,
I just did this on my XP machine:
strtofile( readurl( "
http://www.levelextreme.com/logo/ftfox.gif" ), "testreadurl.gif" )
and opened the gif up in the browser and it looks fine.
Are you getting any particular error? Have you stepped through the code in the debugger?
>Works on Win2K but not WinXP - any idea?
