I have installed RedHat linux for ppc in my G3  desktop Macintosh.
Everything seems to work fine (several commands,
netscape,glint,nedit,etc,etc), except for mouse in xfm in X. I use:
left Opt+-click = button2 (middle)
right Opt+- click  = button 3(right)
and works fine in everyting  in X (afterstep, Netscape, etc..), but when
using  xfm it only displays menus and does not allow select any option.
If I exit X and exec again startx, then the left Opt+-click
(button2,middle) starts to work OK, but right Opt +- click (button3
right) remains showing menus and doesnt allows select any option. (Is
this a clue?).
Any ideas?

Known problem.  Maybe someone's working on it.

Thus spake Antonio Vera to those in comp.os.linux.powerpc:

It's a common fault <somewhere> that causes problems with all applications
which use libXaw (the Athena widget set) or its replacements, as well as
many others. What's happening is that the keypresses you use are
autorepeating, which cause Xpmac to send spurious mousedown events when
you press-and-hold for, say, a menu. This confuses many programs.

The simple fix is to use non-repeating keys e.g. scroll lock and num lock
instead of alt-2 and alt-3. Your Xpmac should have options for this; find
out where it's being invoked from and change its parameters.

You might be able to track down codes for non-repeating keys using
xkeycaps (xkbsel? xkeymap?) and xev; but don't rely on xkeycaps reporting
the state of the keymap correctly.

Of course the above works best if you're left-handed, I suppose; but it
doesn't bother me much and I'm right-handed. The best solution is probably
to buy a 3-button mouse that works with the current {kernel, Xpmac,
mousemode etc.} and use that.
