The program is for my parents who have absolutly no idea about computers, so it must be easy to use.
I installed Windows 7, and after trying to install a few older games I formatted and installed WinXP. The compatibility problems with many older programs on Win 7 is terrible, and until they've sorted it out I will be sticking with WinXP.
I had a look at K9, I will try downloading that. I will also try the above.
