The bar of XMM writes: (Portable) I don't think that this is good, right? Even if I restart XMM, this stays there. I think that this appeared since I updated to the latest version, I am not sure, though.
I think this doesn't matter much because as far as I can see it's just a claim, not really some functionality. XMM still writes to the registry, for instance. A portable app wouldn't do so by itself.
