Looks like you're missing the development packages for GTK and Libart.
You're not saying which system this is on, so I can't tell the exact names.

Thank you!  Feedback is always appreciated (though telling what system you
have and which version of Dia you use helps us help you).

That's because you use a window manager setup where you need to click to
focus the window.  The first click gets used by the window manager.

True.  I personally don't agree with that decision.

There is.  In the right-button menu, under View.

That's not a problem we've run into before.  The newest CVS version has a
diagram tree feature that might help you.

Because it's easy to convert to other formats outside of Dia (using
Imagemagick, for instance).  Besides, GIF is not free and JPG is lossy, a
poor choice for diagrams.

We do.  Maybe it hasn't shown up in your installation, but without knowing
your setup, I cannot tell why.

Right button menu, File->Print ?

Agreed!

If you're using CVS to check out the source, do 
cvs diff >my_patch
Otherwise, keep a copy of the original source and do 
diff -rubB orig_src_dir your_modified_source_dir

This should give a patch that you can send to the list.

Thank you for the feedback, keep it coming.
