The new webmail program has been "uploading" a fairly small file for a half-hour now. I sent the attachment using one of the old programs in a couple of seconds. Anybody else having this problem?
No, it's working just fine for me here. What OS/browser? How did you try to upload the attachemnt? (By clicking the button or by drag-and-drop?) Do you have anything like no-script enabled?
At this point, just cancel it and try it again.
