[imp] message compose (upload) hangs after aborted connected

[Jens-U. Mozdzen]

Hi all,

due to reasons currently beyond our control, an AJAX call used to  
upload an attachment is aborted by the web server.

When using Firebug to watch the network requests, I see it report that  
the request was aborted.

Unfortunately, the (dynamic view) message compose window still shows  
the "uploading attachment" message and I have no way to retry that (or  
any other) upload. Other UI elements do work, I can edit the message  
content etc. and even delete already attached uploads. But new uploads  
are "blocked" by that status message.

Shouldn't the JS AJAX code catch that condition (abort of AJAX call)  
and reset the UI status so I can select to upload again?

Regards,

Jens
