Well, we though about that and here is the key. The latter number is
the good one. So, because ClustalW is stable but ClustalX still
depends of vibrant, clustalX stays beta.
So, ClustalX 1.64b runs ClustalW 1.74. That's all. ClustalX 1.65b is a
platform dependant bug correction (so that is why there is no 1.65b
for all platforms).
Well, we have to clarify it a little bit more, probably for the 2.0
version of Clustal (both X en W) :).

Many thanks to all the users who report bugs or compiled it on so much
different platform. Also, note that it is based on the vibrant
interface (NCBI tool kit) and NCBI people helped us a lot in tracking
platform dependant bugs.

That is a team work men ! :)))). Julie is always doing the code for
both ClustalW and ClustalX and it stays a collaboration between all
the authors of the ClustalX paper (and all the users).

I advise everyone interested in Clustal problems and workaround to
read the october computer corner in TiBS. The answer of you question
was in it and probably other workarounds regarding several specific
sets of sequences.
And hopefully, such problem reports will help us improving the Clustal
Thanks to all!
