Hello all I found strange bug when working with gnus 5.10.x and No Gnus with Emacs from CVS. When i use default summary spec and Cyrillic-KOI8 environment, summary lines is not updated in run-time (you can see this on first image - gnus-brocken-summary.png, in this image, first two articles is readed, but not marked by gnus). Also with this error, not working mark-processing functions, such as, spam-move, etc. With default language environment, all works fine - you can see this on the second image - gnus-default-summary.png - this image was taken from gnus and emacs without any customisation. And i can work-around this bug with custom specifier of gnus summary, such as "%U%R%z %I%(%6{[ %}%-23,23n%6{ ]%}%) %s\n", for example. Results of this, you can see on the third image - gnus-good-summary.png.
