Since the new update, my page keeps scrolling back to the top each time I mark it C. Then I have to scroll back down to find the next one. How to stop this?

Thanks for reaching out to the Community, glenda@a-zrental.

If you're referring to marking transactions as cleared (C) in an account register, it's normal behavior for QuickBooks to refresh to the top of your page after saving transaction changes.

Here's an image showing how it works:
 

I can certainly understand how an ability to not be refreshed to the top of your page after saving changes could be useful and have submitted a suggestion about it as of today.

You can also submit your own feature requests while signed in.

Here's how:

1. Use the Gear icon, then go to Feedback.
2. Enter your suggestion(s) in the Have feedback? window.
3. If necessary, attach a file with your Camera icon.
4. Select Next.
   
   

Your feedback's definitely valuable to Intuit. It will be reviewed by our Product Development team and considered in future updates. You can stay up-to-date with the latest news about your product by reviewing Intuit's Product Updates webpage.

In the event you're referring to a different screen in QuickBooks, if you could please get back to me here with more information on what exactly it is that you're doing when you're being scrolled back to the top of your page. Any screenshots you can provide will also help me to better understand the situation.

Please feel welcome to send a reply if there's any additional questions or information. Have a great Wednesday!
