Hello RodWright,
I understand there has been a confusion with the answers. But, I'm here to help you out.
Let's start with the screen resolution. You can change QuickBooks's window size by going to the preference settings. Here's how:
- Click on Edit.
- Choose Preferences.
- In the Display section, adjust the screens resolution.
- Click on OK.
For merging windows permanently, that isn't possible. I will send feedback to our product developers about this.
If you have more questions, please let us know.
