Hey Daniel,
Many thanks for this tremendous post.
This is exactly what i needed to get me started in troubleshooting
this issue.
I will have a look at integrating into my system and see how it works.
I do have file upload forms which means i would also be looking at a
solution/assistance for this problem as well.
Thanks so much mates, this is great.
Cheers,
