Hi Maik,

Adobe Deflate is the base of LZ77 algorithm not patented. LZW is based on LZ77
with improvements but patented (now expired). Typically LZ77 must be processed
by LZW by retro-compatibility for decoding purpose (the inverse will be not of
course).

So the limitation in NX is a non sense, but after all it's a proprietary
software which will don't care about interoperability.

Gilles
