Never-ending submits

[mathdon]

Almost every time I submit a post recently, the browser says "Waiting for www.hifi...." which never seems to end. If you close that window you find that the post has indeed been submitted, but the message suggests that it has not. This is both annoying and has clearly led to users submitting the same post multiple times. Can anything be done about this?

I will try to submit this only once .
