What is the difference between unregistered and registred                   version?

Unregistered version shows only 5 connections at time. There are no other limitations. 

How accurate is your program?

At the moment it is as accurate as the MaxMind GeoLite City database is. I believe that (with your help) it will improve in time.

No matter where I browse WIPs shows still the same location. Why?

Probably you are connected via proxy server. Are you using some kind of web accelerator like Google Web Accelerator? Or maybe you are using one of anonymous surfing services (e.g. JonDo)? If answer is YES, then WIPs is rather useless for you, although it will still show connections made by, for exmple, bittorrent clients.

Why I always get 'traceroute failed' when I click on remote locations?

There may be several reasons for that: 

    your ISP blocks ICPM packets

    your router blocks ICMP packets

    your firewall...well...blocks ICMP packets 

I'd suggest a little experiment: at command line type tracert google.com and press enter. If tracert completes succesfully then I am to blame.

Lines and points that indicate remote locations are blurred, I hardly see anything! 

Right click on the desktop to open Screen Control Panel and go to Settings/Advanced.  Then you should look for anything named OpenGL. Go there and disable wierd things like smootvision, turboantialiasing, whatever they may call it...
