Manually uploading to soundcloud freezes web ui

Hi,

here's an issue we been having recently with Airtime 1.8.2

If a show doesn't get uploaded to soundcloud for whatever reason, then it's possible to go to the schedule and upload it manually by clicking "Upload to Soundcloud". However this means airtime is unusable whilst it carries out this task. Changing to another view (eg playlist builder) results in a connection time-out as does requesting any other page or info. We have shows uploading to SC all the time, so it's not a bandwidth issue, just an issue with the web ui somehow.

thanks

James
