MIDI note input

I just installed 4.5 and am having an issue and wondering I can get some help. I am using a midi keyboard for input. In the past, I could take the program out of note entry mode and play notes on the keyboard to try to come up with some ideas for entry. The 4.5 version puts me into note entry mode everytime I enter a note on the keyboard. I have looked for settings but cannot find any that apply. Can anyone provide an answer as to how I can revert back to the old setting… See more
