I've been using WP to twitter for quite some time and it has been working perfectly, however I recently decided to upgrade to version 2.4.7 and since then this plugin does _occasional_ double posting to twitter (it occurs about 80% of the time). And with double posting I mean that whenever I do 1 post in my blog I get 2 tweets for it.
I do change the post_excerpt (through the wp api) after it has been posted since I want a custom text for the tweet, so the default twitter filter for duplicate posts doesn't help me there.
I only have "New posts" selected in the plugin menu.
Any ideas why it fires 2 twitter updates instead of just one?
