webpage runner - Custom HTTP runner - proxy password not wo

Hello,
I´ve entered proxyuser-name and proxy-user-pw - but this does not work in loadUI 1.5.0 and loadUI 1.5.1-snapshot

tested with webpage-runner and Custom-HTTP-runner

platform W2K3-Server

For reference I´ve entered Proxy-User/PW in Webserver Stress tool 7 and there it works.

Is there another place to store proxy-username/pw ?

During installation of loadUI I was asked to enter this information but I´ve leaved it blank.

regards
lanfan
