File dialog in Emacs under Glux

[B. T. Raven]

i.

I have been using w32 Emacs for quite a while and have gotten used to 
the File Dialog when mousing around the menu bar. I have commented the 
w32 specific stuff out of my .emacs for use under Gnu/Linux but I don't 
see file dialogs there (Fedora 8)even with use-file-dialog and 
use-dialog-box set to t in my .emacs. Does any of you have a clue as to 
why can't see file dialogs in Fedora. I don't have a Web connection to 
that machine and so I just downloaded the 22.1 sources, transferred them 
to the Fedora machine with a flash drive, and built them there. Did I 
miss some necessary toolkits. The About Emacs screen shows i686 with X 
toolkit and xaw3d.

ii.
I have used xmodmap to make mouse left handed with "pointer = 3 2 1" but 
I have to click twice to execute. Is there something I can put .xinitrc 
or .xmodmap or Xmodmap to make the mouse work like under w32 (one click)?

Thanks,

Ed
