Dia on Windows (0.96.1) old build. Issues may be fixed ?

["Kerry, Richard" <richard kerry siemens com>]

I've recently installed Dia, having seen a diagram in the Bugzilla
documentation similar to what I wanted to do.
I seem to have found a handful of problems, some of them are issues
where the help-file doesn't appear to be correct.  I don't know whether
I'm misunderstanding something or the help is not the correct build for
the program.
 
1.
I'd like to change a drawing from compressed to uncompressed XML.  The
default is compressed but I want to version control my document so
prefer it to be uncompressed xml.  I needed to do this by saving with a
new name, renaming, deleting to get this to happen.  Should I have been
able to do this just by clearing the "Compress saved files" option and
resaving ?
2.
Right-click on the canvas.  Nothing happens.  The manual says do this to
get Select Connected/Transitive Objects menu to appear but it doesn't.
That's only available from the Select menu.
3.
When I open existing diagram file, I prefer canvas to be same size it
was for last edit, .
3a.  Subsidiary windows (layers, diagram tree) open very small first
time.  Though on a subsequent run they do pick up the size they were
before.
4.
Can't change a line to a PolyLine.  I've drawn my diagram with Lines.
On occasions I've found that I want to route one around another item.
In this case I've needed to create a new PolyLine for this.  Would it be
possible to remove the distinction, at least internally, and allow
corners to be added to Lines.
5.
Editing Text.  The Delete key deletes the object not the character and
is thus different from most other Windows programs.  Also ctrl+arrow
doesn't jump by word.  I've seen an entry in the Archives indicating
that some change have recently been done in this area and also a
discussion about a new Installer build, the first since 2007; hopefully
this will come soon.
6.
Can I render to png (say) from the command line ?  Yes I can.
Actually the Help files say nothing specifically about the command line
except for a handful of references in passing.  I have found that dia
--help has a bit more to say but it should be in the manual somewhere.
And not even -?, --help was mentioned in the current manual.
