Why does an invoice item create graphic errors when I move the item on the invoice to be below or above another item?

Hello Upstream1,

I can see how dealing with graphical errors can slow down your progress and I'm here to help. QuickBooks is designed to help you get your work done faster so you can save time for the things you love. 

Based on what you've described, I'd recommend clearing cache and cookies on your browser. Clearing cache and cookies is a great way to clean your browser making it run smoother and efficiently. Here's an article that shows you how to clear cache and cookies on your browser. I encourage you to give this a try and let me know what happens. If you're still getting graphical errors, feel free to send me a full screenshot in the comments below. Make sure to include the URL of the site in the screenshot. I'd recommend covering any personal info that may appear in the screenshot. 

Keep me posted on how you make out.
