Re: Exmh 2.7 Flist much slower?

I figured out the packing bug that makes the ftoc lines preference
not match up with your expectations.  The simplest fix to try is
at about line 585 in exwin.tcl, make it look like this:

    set exwin(ftext) [Widget_Text [Widget_Frame .ftocframe ftoc Ftoc $fixed] \
                                $exwin(ftextLines)]

where the packing option should be $fixed, not $expand.  The current code
has $expand, which means that the message display and and ftoc display
both compete for extra space available.  Changing it to $fixed means it
stays the size requested by the text widget.  The actual fix I'm using
is:

    # Folder display (Ftoc).  If this shares the window with the message
    # display, then do the non-expand (i.e., fixed) packing.  Otherwise
    # pack it so it with expand enabled so it fills up the window.
    set pack_opts [expr {$exwin(toplevelMsg) ? "$expand" : "$fixed"}]
    set exwin(ftext) [Widget_Text [Widget_Frame .ftocframe ftoc Ftoc $pack_opts] \
                                $exwin(ftextLines)]

I haven't tested with the toplevelMsg yet, however, but it should do
the right thing.
