Synergy is a great program to control 2 computers with one mouse and keyboard. But it doesn’t appear to work with Windows 7. Is there any options? Well yes!
I found another program that works well with Windows 7. It’s called Input Director and works quite well – in fact I think better than Synergy does.
It certainly is much easier to configure, where you define a master and slave (in fact you can have many slaves), and can selesct what subnets (or individual hosts) you can accept connections from (on the slave of course).
