@JohnB reminds me of a bug I had in Photoshop. After I typed a letter into the font name field it would highlight it so I'd have to retype the first letter
QuickBooks is just one big steaming pile of UX crap. They hijack a lot of OS shortcuts, it makes for a miserable experience. For example, Ctrl + A pulls up the Chart of Accounts regardless of where you are. So if you want to highlight everything within a textbox...sorry nope not with that shortcut
I have QuickBooks but I barely use it. Only time I access it is either to look for a dealer that might be by a show I'm going to, or when one of my coworkers is out and I'm covering
