As Jerry has pointed out, the latest version of 'treeview', 
released about last March, now accepts 500 taxa.  The main web 
page for 'treeview' still gives 200, but the online help (which 
uses your web browser to connect you to the 'treeview' site) has 
the higher number.

Although the newest Mac version imported my 270 taxa file and 
could change the tree type, etc., the whole tree was compressed 
into about a quarter-page chunk in the centre of one page; the 
help says trees can be printed over more than one page but I 
couldn't get the tree to be expanded to do this.  The program 
exports PICT format and further processing in a drawing program 
may be required to convert the tree into a readable printed form.

I originally ran 'treetool' under Solaris 1.1 and may have used 
the precompiled version at some stage before building my own.  
When I upgraded to Solaris 2.4 I decided to rebuild things 
properly to the new OS and that required modifications to the 
source for GDE and 'treetool'.  My only disappointment at this 
stage is that I can't find the source for the static libraries 
'treetool' uses during linking and so I can't build it for LINUX 

Any further discussion of this would be more be appropriate I 
would think in 'bionet.software' (and the moderators presumably 
would agree).
