Here is a one page test for the problem. I've tried this on different computers
with Windows and OSX. Below is very basic, though messy, example of the
problem. It may end up being a bug in CF or something, or I may just be missing
something about uploading binary files...but I've tried all the option I could
find with no success.
The code does the following
1. creates a text file
2. creates a zip file with the text file
3. tries to unzip the file to make sure it is fine
4. uploads the file (processed by a <cfelse> block at the bottom)
5. tries to unzip the file uploaded
The error occurs in step 5. CF just can't unzip the uploaded file, but I can
unzip it using other tools.
