Hello there.

I'll help you perform troubleshooting steps to resolve the issue of being unable to see the magnifying glass when hovering the mouse into the numbers.

You can first check the display settings of your computer. Refer to this article for the troubleshooting steps for screen issues: Fix screen issues in QuickBooks Desktop.

If the issue persists, I recommend you download QuickBooks Tool Hub.

Here's how:

1. Close QuickBooks.
2. Download the most recent version (1.5.0.0) of the QuickBooks Tool Hub. Then, you can save the file somewhere you can easily find it (like your Downloads folder or your Windows desktop). Note: If you've installed Tool Hub before, you can find out which version you have. Select the Home tab. The version will be on the bottom.
3. Open the file you downloaded (QuickBooksToolHub.exe).
4. Follow the on-screen steps to install and agree to the terms and conditions.
5. Once done with the installation, double-click the icon on your Windows desktop to open the tool hub.

Once done, proceed with running Quick fix my program. Here are the steps:

1. In the QuickBooks Tool Hub, select Program Problems.
2. Select Quick Fix my Program.
3. Start QuickBooks Desktop and open your data file.
