problem updating caption with escape sequence

[Zajcev Evgeny]

Hello.  Thanks for one of the greatest software ever!

I recently discovered problem with dynamic update of caption string.

In my ~/.screenrc i have:

    caption always '%{= Kw}%-Lw%{r}(%{+b .W}%50>%n%f*%t%{r})%{-b .w}%+Lw%<'

i started two windows with shell in screen.  In first window i
typed:

    $ print -Pn "\ektest start\e\\"; sleep 3; print -Pn "\ektest
    done\e\\" <RET>

In caption string "test start" appeared, then i switched to next
window and wait for 3 seconds.  After 3 seconds nothing changed, "test
start" has remained in caption string.  On the other hand, if i dont
switch and stay in first window then "test done" appears.
