Mail Queue : bug with factorySendMail method?

Hello - I am a big fan of Mail_Queue and have used it several times in the past. During my first usage of 1.1 I ran into a problem sending emails in the queue. (I was able to get emails into the queue just fine.) I was getting an error that said there was a call to an undefined function, send(), on line 365 (in Queue.php) in sendMail(). Seeing other posters write about the sensitivity of the driver variable, I took a closer look. I noticed that factorySendMail() contained this line of code: unset($options['driver']); I also noted that factorySendMail() is different in 1.1 (than in 1.0). I commented the unset code out and it worked! I looked at the change log and saw, "Fixed error in factorySendMail()". So, apparently there was an issue with the driver parameter for others in 1.0? I wanted to make the development team aware of this bug. Thanks, Stephen
