Your participation in this thread is much appreciated, CJ86. As per checking, we don't have an open investigation regarding the estimate's side panel not disappearing when hidden. No worries, I'm here to help you handle this matter.

The empty column visible when generating an Estimate works as designed. Once you select a Customer:Job in the designated field, the customer's complete details and existing transactions, along with their balances, appear on this part of the page.

As you've mentioned, we can minimize this section by clicking the Hide history > button.

If the customer history portion of the estimate doesn't shrink when clicking the Hide button, let's reproduce the steps in installing and running the Quick Fix tool from the Tool Hub to narrow down the result. Here's how:

1. Close your QuickBooks company file.
2. Click this link to download the latest version of the QuickBooks Tool Hub (1.6.0.5). Store the file in your most accessible folder for easy access.
3. Open the downloaded file, QuickBooksToolHub.exe, follow the on-screen installation procedure and agree to the provided terms and conditions.
4. Once the installation is complete, select the QuickBooks Tool Hub icon to open the software.
5. From there, choose Program Problems, then Quick Fix my Program.
6. Launch the QuickBooks Desktop company file.

Nevertheless, please follow Solution 2 of this link if you encounter the same problem: Repair your QuickBooks Desktop for Windows.
