Please allow at least 2 windows open for the same vendor if the same person has them open.

While I'm entering an invoice, I like to reference the previous invoice to check my work. While I have my invoice I'm working on up in one window, I open another window to check the previous invoice under that vendor. Then once I'm done reviewing, I go back to submit my current invoice, and it shows an error screen saying the vendor is locked because I'M the one in it. The locks take 5 minutes to clear and that can become very annoying, especially when I finish filling out the information and I can't save it because of this lock.
