AquaPlane The error message doesn't metion any file or file type... This problem occurs generally when I'm trying to view an image in either IE 5.5 or Netscape 4.7 (Communicator). I can't even figure out a way to force the error, it's just intermittant.
I've given your suggestions a try though - if I run into the error again, I'll drop you a line.
Thanks for all of your help!
