I get this error with Zinc only when I'm behind a proxy, if from the Monticello Browser I try to see the changes of a certain package:

'Could not load FileSystem-Core-MarcusDenker.99.mcz: MessageNotUnderstood: ZdcSocketStream>>position'

Is this a knows issues?

If not I can provide more details.

I noticed this on the latest Pharo 3 image.

Cheers,

Andrei
