The upcoming release of Jing for Windows is going to include proxy support--including authenticated proxy support.

We're looking for a few people who have tried Jing in their school or workplace and have been unsuccessful due to proxy server conflicts. We've done a lot of testing, but it would be nice to try Jing in the greatest possible variety of conditions. Can you help us verify Jing works in your setup next week? We want to especially make sure it works in authenticated environments. If you're interested, please contact us.

P.S. We haven't heard of Mac people having proxy issues, but if you are, let us know!
