The more important fact > is that C-g "breaks" the display again, which is... unexpected. Could the reason for this problem somehow be related to gnus-horizontal-recenter, which is called by gnus-recenter basically whenever you do something in the summary buffer? If you disable this horizontal recentering (e.g., by setting gnus-auto-center-summary to the value 'vertical'), does the problem go away?
