I'd agree there is a problem, with the image. I looked on 3 computers 
and I have 8 copies of that file, but all are identical copies, so its 
not something I can do anything about. Either Svetlana produced a pdf 
file with a bad image, or I've got a corrupted pdf file 8 times over.

Carl is not saying that there is a password being requested, but that a 
password is apparently being looked for without the users knowledge. But 
I am skeptical of this, since I would expect others to find it if this 
is the case. Hence I suspect if there is code attempting to look for an 
eBay password, that code has been added somewhere between the web server 
and Carl's computer. I do not believe the web server is compromised in 
any way.

If the web site was trying to get an eBay password and ZoneAlarm was 
able to detect this, then everyone with the pro version of ZoneAlarm 
should see it. But so far there is not a single report of this, other 
than from Carl.

Just to convince myself even more the pdf file is not in any way nasty, 
I did a search for the string "ebay" (ignoring case) in that file and it 
is not there.
