If you login to SciDrive, and try to upload a file to the root folder right away, without navigating through the directory tree, then the proper warning is not displayed, the upload is started, but gets stuck with an error message:
"Can't upload the file: Not Found"
Any subsequent uploads become impossible until you reload the page, because the stuck upload blocks all others.
If you start navigating after logging in, and then try to upload a file to the root folder, it displays the correct warning, and the upload is not started.
