[Message part 1 (text/plain, inline)]

Hi

When using emacs in -nw mode, the cursor seems to hang quite often leaving back a cursor block. 
The block is redrawn correctly if the window is resized or refreshed. I have attached a few low-res screenshots of the behaviour.

How to reproduce:
In a terminal 
1) start emacs (emacs -nw)
2) switch to scratch buffer 
2) Change to c mode (M-x c-mode)
3) type 'if (aa == 1)'

You should now see (a green) cursor block between 'aa' and '==' like the screenshot.

Tested on:
Freebsd, Debian, Gentoo, Ubuntu

Tested with terminal:
Gnome-terminal (term=xterm || term=linux)
xfce-terminal  (term=xterm || term=linux)
rox-terminal   (term=xterm || term=linux)

Cannot reproduce with 
linux console (term=linux || term=xterm)
xterm (term=xterm || term=linux)

There are many places where this bug could be, and im not too sure if its the terminal, the major mode or emacs that causes it.


Best Regards
Kim Carlsen
