Check Box always empty for facebook!

I’ve been using this plugin now for a few years and one issue has always drove me bonkers. At the bottom of the “new post” page I have to recheck the box next to Publish to facebook. The twitter box always remains checked. The facebook one only about 30% of the time. How can I get it to remain checked at all times? This is creating a huge problem for my new posters, because they don’t think to make sure there is a check mark in the facebook box. IN their defense, they shouldn’t have to…I paid for this to work right all the time…not only sometimes.

Plugin Version: 3.5.1 (API Version: 2.18.9 [ID:5722]) [Pro – Multiple Accounts Edition]
