I just upgraded to 4.3pre8 from 4.2 and I noticed that now when I click on the dropdown to change buffers and type a letter or two to jump to a particular buffer on the list, it actually types those letters in the buffer as well as using it to select from the buffer list. (e.g. I am working on an file called 'index.php' and I want to switch to a file called 'add.php'. I click into the buffer list at the top of my window and hit the 'a' key. The buffer changes to add.php, but also types the letter a into index.php, so I have to go back and delete/undo it.)

Has anyone else experienced this, or, even better, found a way to fix it?
