At the moment I have a very basic html form - it has 4 form fields (file-pickers) and a submit button.
If I submit the form with no files selected, it continues to the next page.
If I add a small (2MB) file into one of the file pickers and submit the form, it continues to the next page.
If I add a large (32MB) file into one of the file pickers and submit the form, it never leaves the page (the 'working' icon spins around in IE, but it never actually proceeds).
This problem appears to be relevant on the form page only (not the form processor) - I've changed the form action to a page that does not exist - and the outcome is the same in all 3 scenarios listed above,
Any ideas on how to fix this?
