Dear Lanux128,
I've actually been quite successful so far in my search.
The following programs show split screens with previews:
Microsoft Office Sharepoint Designer (FREE) -- Horizontal display AND both sync
CoffeeCup
Free HTML Editor -- Horizontal display (no sync)
HTML Pad (about $35) --Horizontal OR Vertical display (no sync)
Trellian WebPage (FREE) -- Horizontal (no sync)
EvrSoft First Page 2006 (FREE or Pay?) -- Horizontal with sync (but questions about support, registering, stability)
So the best ones, with sync that is, are:
Microsoft Office Sharepoint Designer (FREE)
and
EvrSoft First Page 2006 (FREE or Pay?)
and the only one with my preferred Vertical split (but no sync so far)
![Sad :(](https://www.donationcoder.com/forum/Smileys/fun/sad.gif)
is:
HTML Pad (about $35)
How about all that?
