[Plugin: Akismet] false positives & my own comments marked as spam

I’m running akismet 2.2.6 and over the last couple of days when I reply to comments in my blog while logged in, my replies get put into the spam queue. When I approve them they appear ok on the site, but when I check my akismet stats it says that no false positives have been recorded. Anyone else with this problem? Or am I just doing something stupid? (but what – akismet worked well before and I’ve done nothing to it other than update whenever a new version comes out) I guess the last update was buggy – let’s hope it gets resolved soon.
