I ran into this error using ASPSmartUpload while copying and pasting text
from a Word document. Its appearance depended on the text and whether it
came from Word or Notepad. I suspected some funky character was throwing
off the collection count, but they weren't visible even with paragraph
marks visible. I found this suggestion at:
http://www.fogcreek.com/FogBUGZ/kb.html , which seems likely:
"You are probably using MSIE 5.0 and you pasted a curly quote or an
ellipse or some other funky Word character into the bug. Strange as it
sounds, this is because MSIE 5.0 does not post form data correctly when
the form type is "multipart/form-data". The simple solution is to either
upgrade to IE 5.5 or take out the funny characters from the bug you are
submitting."
I tried the problem text using Netscape 4 and things worked fine. My IE
version is listed as 5.00 (but I think I may have seen something about it
listing the wrong value).
