Hi Paul
This was a problem I encountered as I have lots of information in
titles: working directory in xterms, filename in emacs, doc title in
netscape, etc etc.
The solution, for me anyway, was to use
Style "*" Icon none
which just produces the icon title bar (I like things minimalist anyway!).
This hilighted what I thought were two bugs in fvwm:
1. The icon title bar width is calculated only when the application is
iconified for the *first* time. If the title subsequently changes
this width is no longer correct.
The following patch causes the icon to be redrawn on *every* iconify
for applications with no icon pixmap (the overhead is pretty trivial).

AutoPlace(tmp_win);
tmp_win->flags |= ICONIFIED;
tmp_win->flags &= ~ICON_UNMAPPED;
2. If the icon title changes whilst the application is iconified the event
is trapped and the title changed, but the width not recalculated.
The following patch redraws the icon on such an event for icons with
no pixmap. Note that this will cause the icon to move if it gets wider and
no longer fits its current slot in the iconbox.

I have my iconbox running horizontally across the top of the screen,
and a long document title in netscape can cause the icon to be almost
half the screen width. This doesn't matter as I save so much vertical
space by not having icon pixmaps. I discriminate applications by using
different colours on the decorations.
Try these patches and see if they do what you want.
BTW, Chuck, are you going to include these in the next beta? I can't
remember what you said last time.
