Keyclone and Vista problem

I know this problem involves Vista and is probably not supported for Keyclone, but I thought I'd describe what is happening anyway to see if anyone had any insight on whats going on.

The Vista PC is my main and I have two other XP machines as clients. Sometimes when I press the '9' key which mounts all my characters, it shows up as ALT-9 on the XP machine. This seems to be occurring when I've previously used an ALT sequence before hitting 9. I wonder if somehow Keyclone is not clearing the ALT state when it sends to the XP machine.

(Note: this is not just happening with the '9' key but with lots of keys, maybe all keys, I just gave that as an example.)

I'm running two WoW clients on the Vista machine and the problem doesn't occur with the second clone under Vista. When I hit 9, I get 9, not ALT-9.

I remember reading there were a lot of issues trying to get Keyclone to handle ALT/CTRL/SHIFT states correctly. Maybe the problems still exist if Vista is being used.

I've reverted back to using Multibox for the XP clones and its working great, but I miss the round robin capability of Keyclone.
