I use the search results window.
Left click the file you're d/l (if it's not already highlighted), then right click and a window should pop up.
If they have the chat feature and it's enabled you might be lucky.
There is a bug though - some people have 2 chat windows pop up.
If that happens to you, I'm afraid I've not heard of anyone who can use it successfully. But there hasn't been much input on the forum about it, no-one has posted a success with 2 windows.
Anybody out there have any joy with 2 windows when using 'Chat' ?????
Good luck anyway
