I dealed all the day to get everything around UVNC SC up & running, but I'm still missing to point about how to get the helper side to see something

I followed the step-by-step-instructions on the web site (+the FAQ entry [topic=3278][/topic]); the connection seems to work - but I cannot see anything. As soon as the connection seems to be established, the icon in the systray (WinXP) shows no context menu, I'm not getting asked if I want to accecpt the connection, I get no screen.
The only thing I have is a 1-pixel bar on the very upper part of my desktop; approx. filling 75% of my screen's width. When pointing the mouse over it, the cursor switches to the hourglass, but I cant do anything useful

Does anybody has an idea how to get rid of this?
Thank a lot!
