Welcome back to the QuickBooks Community, MrMark. This isn't the kind of feeling that I wish you to have about resizing the Edit item section and we know how much time it can take when something isn’t working the way you need it. I'll ensure you'll be routed to the right person so you're able to report this matter.
Our QuickBooks Desktop Support Team has the tools to pull up your account in a secure environment which we're unable to do it here in the Community. With this, I recommend contacting them so they'll be able to investigate the cause of why the Edit edit won't allow you to resize the window.
Then, you can open this article to view different details on how to troubleshoot font, sizing, or other display issues in QBDT: Fix screen issues in QuickBooks Desktop.
Lastly, you may refer to this article to see steps on how you can delete or make any changes to your item list in our program: Add, edit, and delete items.
I'm only a few clicks away if you need further assistance with customizing the appearance of your Item window in the QuickBooks Desktop account. It's always my pleasure to help you out again.
