synergy-foss using Windows 7 as Synergy Server and a Macbook Air (OS X Lion 10.7) as Client

Question

my synergy config looks like following:

section: screens
    mac-air:
        halfDuplexCapsLock = false
        halfDuplexNumLock = false
        halfDuplexScrollLock = false
        xtestIsXineramaUnaware = false
        switchCorners = none +top-left +top-right +bottom-left +bottom-right 
        switchCornerSize = 10
    VIE-CA:
        halfDuplexCapsLock = false
        halfDuplexNumLock = false
        halfDuplexScrollLock = false
        xtestIsXineramaUnaware = false
        switchCorners = none +top-left +top-right +bottom-left +bottom-right 
        switchCornerSize = 10
end

section: aliases
end

section: links
    mac-air:
        right = VIE-CA
    VIE-CA:
        left = mac-air
end

section: options
    relativeMouseMoves = false
    screenSaverSync = true
    win32KeepForeground = false
    switchCorners = none +top-left +top-right +bottom-left +bottom-right 
    switchCornerSize = 10
end

I have a Windows 7 machine running as the synergy-foss 1.4.5 server with a Microsoft Wireless Keyboard 3000 attached to it. As a synergy client I'm using a Macbook Air with OS X Lion 10.7.2 (synergyc from macports)

Now the problem I have is that some keys are not or wrong recognized on my mac, for example pressing the hash key does a screenshot instead of inserting a hash and pressing Alt+Gr behaves like the Mac-Key.

Do someone know a way how I could get it fully working with correct keyboard mapping on both machines over synergy?
