Thanks for looking into this for me. So far what has happened is that it does not actually replicate any keyboard commands. I have the script from their site running along with rebinds of all of the movement keys to follow command macros, but the only thing that gets sent to the second client window are mouse clicks and only if I hold down the OEM key. Even the mouse clicks will only replicate the first mouse click. No other commands are being sent over to the second window. In order to test this I even opened chat on the secondary account to capture any keystrokes and none were captured. I've had this happen both in compatibility mode as well as normal. I looked and the HKN site specifically states it only supports up to Windows 7 and there are no threads there in regards to work arounds for the compatibility issue, therefore I took them at their word that it was unsupported.
