SBX tile server problem


Some weeks ago internet connection in my workplace changed. Before, it was a direct connection, now we need to use a proxy.

I configured my computer to access the proxy. I can connect to internet, but it doesn't work with SBuilder tile server.

Google Earth program (alone) works correctly and ask me proxy identification.

With SBuilder, I'm not asked anything, and no tiles are downloaded (Google tiles with GoogleServer.dll).

Could you help me to solve this problem if possible?
Is it possible to configure SBuilder to make it know it needs a proxy?

Thanks for help.

(all still works correctly with my home personnal conection, but very slow with a modem!)

I use fast connection to gather tiles, then I work whith cache at home to draw.
