It appears to be working, just uploaded a 20MB build, and a 25MB build. The little bar that displays the progress of the upload raced across and was not a true display of the upload.
I then turned off my anti-virus Kaspersky software and did another upload of a 41MB build and the progress bar acted correctly as a demonstration of the upload progress.
Whatever the Dev's have done, seems to have fixed the problem! Cheer! :D
Thank-you Doug!
