Hummingbird Conflict?

I have noticed a couple of odd things with Hummingbird active: 1) starting Upfront requires a second click of the Upfront menu item 2) having done a plugin test, I appears it was Hummingbird that was preventing the HTML/CSS/JS editor from displaying correctly.

As for 1, I found a thread that suggested I disable minification, this didn't work for me.
