this opensource (free) tool might be of help... http://sourceforge.net/projects/synergy2/ Description from the site... Synergy lets you easily share a single mouse and keyboard between multiple computers with different operating systems without special hardware. It's intended for users with multiple computers on their desk since each system uses its own display.
I use Synergy on my two work computers and it does exactly what it says on the tin, in fact it is in some ways better than the keyboard switch I have used at other banks, in that it allows copy and pasting between the two machines. Stew
I use my second trading computer exclusively for viewing porn. Why on earth would anybody give that up to TRADE on it during the day?
