According to the Score Submission Guide the size limit for files being uploaded is 100MB however several times today I have attempted to upload a file which is a little over 2MB.
I rely on a dialup connection, so transfer speed might be a problem as the failure always results in "The connection to the server was reset while the page was loading."
Hmm... I think that is quite hard to fix... I think it is just the server timing out, but I'll try to see if I can somehow increase the PHP upload timeout interval. If anyone has any experience with PHP, suggestions are much welcome.
