Re: arachnophilia undo/redo

Henning thanks for the help.  I need to go and do some more research 
now.  Just to quickly tell you what is eliminated:

I am definitely using the packaged SUN versions from non-free.  All my 
versions of java are:

sudo update-alternatives --config java
+        1    /usr/lib/jvm/java-6-sun/jre/bin/java
         2    /usr/bin/gij-4.1
         3    /usr/lib/jvm/java-1.5.0-sun/jre/bin/java
        4    /usr/lib/jvm/ia32-java-6-sun/jre/bin/java
         5    /usr/lib/jvm/ia32-java-1.5.0-sun/jre/bin/java

Debian is 'pure 64' although it runs 32 bit emulation java VM as well.  
Using them didn't solve the problem.  I don't have a chroot or a full 32 
bit system to try this on so the possibility of it being a 64 bit 
problem will have to go unexplored for a while.

That's good information - I will try downgrading the java packages all 
the way to etch as my first experiment.

And that will be my next experiment.  There are likely looking 
configuration files in /etc/$JAVAVERSION.

If I get that far I'll try that as my third experiment.

Yes I was wondering about this.  Arachnophilia was the bees-knees when I 
was a windows user in 1999 but I am realising it has this limitation 
over all the great gpl software I use now I have escaped to the world of 
GNU/Linux.

I have tried Bluefish not so long ago - I didn't mind it.  One thing 
that draws me to Arachnophilia is its simplicity for html, css and 
javascript work.  Now I am actually finding my fallback - the latest 
version of gedit - is getting me almost as productive as I can be with 
Arachnophilia.  But Arachnophilia is unparalleled as a cross-platform 
tool for training people in html coding.  I have been designing for a 
while a course based around Arachnophilia and GIMP.

thanks again for the input.  I have a few good lines of research now.
