QSJ 3.3 Standard failed only with Windows 7 client

Hello,

I am using QSJ 3.3 standard P3596 on my application. The application works fine for any Windows XP client user but it gives a blank page to any Windows 7 user.

Once a windows 7 client user submit login, he gets a blank page and his URL is at http://192.168.1.157:8888/rtr/login-action.vsj?j_vsj_login=true

I don't know if there is a way to get around that.

Many thanks,

Vincent
