Your prompt doesn't appear to be formatted correctly. At a quick
glance, it looks like you are starting the prompt with a "non printing"
escape sequence (\[) for bash, but you never close it. Take a look at
the bash man page, specifically do a search for "begin a sequence of
non-printing characters" under the PROMPTING section.
Each of your color codes should be enclosed in that type of a sequence.

I use bash and have a custom prompt that includes some
coloring (which includes non-printing characters, of course).
When in an xterm, I can always use ctrl-a (beginning-of-line) to return
to the beginning of the line, and it always goes to the correct cursor
position.
When I start screen, if I have text that wraps onto more than one line,
and I use ctrl-a, it backs up too far, into the middle of the prompt.
If cursor forward, the prompt is overwritten by the text as if it was
shifted left a few characters.
Is there any way I can work around this, other than removing the
non-printing characters from my prompt?
Here's an example prompt you can try:
PS1="\[\e[0;42m\u\e[0;49m\] "
which is just your username in green followed by a space. Try typing a
line that wraps, and then do beginning-of-line.
I am using screen 4.0.2.
Thanks for any help,
Bob
