I have a problem with Mosaic 2.0 under VMS. It enters a CPU loop when I access
a Gopher HTML document which has an inline image for which the URL is specified
as "./Logo.gif". The CPU loop is probably caused by an improper Gopher type for
a gif file. I am not sure whether this is general Mosaic problem or a problem
specific for the VMS version.

I would like to know the best way to fix it. I made the following change:

************
File KVI$ROOT:[KVIMAIN.WWW.MOSAIC2-0.SRC]GIFREAD.C;2
  363   /*	while (GetDataBlock(fd, (unsigned char*) buf) != 0) F.Z. */
  364   	while (GetDataBlock(fd, (unsigned char*) buf) > 0)
  365   		;
******
File KVI$ROOT:[KVIMAIN.WWW.MOSAIC2-0.SRC]GIFREAD.C_ORIGINAL;1
  363   	while (GetDataBlock(fd, (unsigned char*) buf) != 0)
  364   		;
************

because it turned out that GetDataBlock kept returning a value of -1. This now
prevents the CPU loop, but the inline images are not displayed correctly. Is
there a better way to fix it? Or is the only hope that that the owner of the
document fixes the URL for the image?
