Send doesn't work with IronAHK on OSX

[miconi]

What doesn't work:

Following Script.ahk:
^j::Send "b"

invoked in terminal with:
ironahk Script.ahk

doesn't send "b" to any application and produces following terminal output:

Nov 26 18:23:25 MacBook-Air-Micha.local mono[23287] : kCGErrorInvalidConnection: CGSGetWindowTags: Invalid connection
Nov 26 18:23:25 MacBook-Air-Micha.local mono[23287] : kCGErrorFailure: Set a breakpoint @ CGErrorBreakpoint() to catch errors as they are logged.

What works:

Example.ahk included in the IronAHK installation archive.

Configuration:

OSX Lion 10.7.2
Mono http://download.mono-project.com/archive/2.10.6/macos-10-x86/1/MonoFramework-MDK-2.10.6_1.macos10.xamarin.x86.dmg
