I've recompiled 1.5.1 with Qt 4.2.3 and here is what I find:

- Italics work properly in Qt 4.2.3 (but not in Qt 4.3.0).
- On my machine (PowerBook G4, PPC, 1.67 GHz, 1 GB rAM) I find no
speed penalty between Qt 4.2.3 and Qt 4.3.0, when paging through
the User's Guide (29 s for both).
- In relation to bug 3307: Copying from the Qt 4.2.3 version to
Word does not work. Copying from Qt 4.3.0 to Word works.
So, as far as I can tell, the basic trade-off between Qt 4.2.3 and
Qt 4.3.0 is visualizing onscreen italic fonts correctly, versus
ability to copy to Word.
By "Word" I assume you mean some external application, right? Or is
it really Word in particular? (What about Text Edit, or Mail e.g.?)
Actually, copying from Qt 4.2.3 to TextEdit or Mail works fine for
me. It is only copying to Word that does not work. I am able to
copy special characters too (äîôéç).
What about speed difference when typing in insets? Since you have a
relatively fast PPC Mac, it would be good to test while watching
the Activity Monitor for how much processor time is consumed by LyX
while typing.
I tried what you suggested by typing in the figure caption of a
float, while watching the Activity Monitor. It is a little
subjective of course, since it depends on how fast I type. But on Qt
4.2.3 I peaked at 69% CPU time, whereas on 4.3.0 I peaked at 46%. So
this does confirm the performance penalty of 4.2.3 with insets. On
my Mac, I couldn't tell the difference without looking at the
Activity Monitor.
If anyone is interested, I put up my compiled versions of 1.5.1 with
Qt 4.2.3 and Qt 4.3.0 at http://bio7.mech.columbia.edu/~gerard/
Thanks for your efforts here.

I am glad to help. LyX has been a tremendous boost in my
productivity. I can write class notes for an entire semester, chock
full of equations, in a single LyX document (easily up to 100 pages
of notes). I can scroll up and down, make changes on the fly, with
no performance penalty (on 1.3.7, which is what I have been using
until now). In the past, when I used Word with MathType, I couldn't
get past twenty pages of equations without creeping down to an
excruciatingly slow response.
