/me must double check the file format ...

Well I was thinking that the arrow ends should have some sort of an active
target area and that by clicking neat the end of an arrow you could change
the shape at the end of the arrow.  Trying to go for the direct
manipulation kind of idea.

I was also thinking that we might also be able to go for the more
conventional menu item/dialog approach, Visio, Smartdraw et al. have
something like Format Line Style.
I'll try and post screenshots of the behaviours I have seem

To be pedantic this is repitition not redundancy and the thing to be said
about it is that it is confusing and bad usability.  Not sure if the Gnome
HIG explictly recommends against duplicate menu items, I'll try and find
it this weekend hopefully.

To help old users it might be worth having the duplicate for only one
release.
Conceptually the Layers are part of the view or part of the Document, and
the properties are the properties specific to the current object.
(If we later wanted to add File, Properties it is a bit messier though.)
The bug report includes more of my objectsions to the whole concept of a
Dialogs menu, ... must resist temptation to make pun about GIMP being Lame
... too late...

I'll try again and make it my priority, my brain is in a better state now
than it was last time I tried.

Not important but I thought I might mention it anway, I previously had a
few differnt GTK Windows applictions all sharing the same GTK.  (Pan,
Gaim, WorkRave and others I forget but I installed just about every GTK
windows appliction I could find.  The shared gtk for windows is avialbe at
http://www.dropline.net as far as I can remember).

but not a release blocker and I filed a report.

I think it nearly is that simple.

I should warn you that because of work and a certain beligerrant Operating
Systems Manufacturer refusing to allow me to instal the software because
they no longer provide support for my perfectly adequate operating system
that I have been forced to squander many hours upgrading to 'Newer
Technology' and I expect I will have to waste many more hours sorting out
drivers and service packs.
