It sounds as though the terminal description (terminfo or termcap) doesn't
have the correct codes for some cursor motions.  Both of the symptoms you
described could be explained if zsh were emitting the wrong code for "move
cursor left" and then emitting either spaces (to cover up one character) or
clear-to-EOL (for ^U).  A simple "typescript" capture of a brief session
would show what's being emitted by ZLE.

} I was wondering if anyone could offer any suggestions?

My guess would be that there's some incompatibility in termcap and terminfo 
on the two versions of the OS.  Either zsh's configure is choosing the
"wrong one" when you build on the older HP-UX, or the one it finds is not
working properly with the terminal description database on the new machine,
or both.

You say:

} I have my own TERMINFO database I'm using for Thomas Dickey's color
} xterm.

Are you sure zsh is successfully reading that database on both platforms?
HP-UX probably has some utilitity equivalent to "strace" ("truss" on Sun)
that would let you examine the system calls to see which terminfo files
are actually being opened.
