I'm writing some Jamba integration for ISBoxer, and it just occurred to me that if you're having ISBoxer generate the Focus Target macro on switch, you can actually check "On Focus Change Set Master To Focus" in the Jamba options page under the Switch tab. The master will automatically be set to the focus when ISBoxer sets it, if that option is enabled If I can enable that option without it saving to your non-ISBoxer Jamba settings I'll hook it up automatically.
