Highlighting Text Not Working Correctly

Hi @Glenn2686370728tk ,

Based on your screenshot, it looks like when you mention "trying to highlight text," you're actually accessing the Comment Tool and utilizing the Drawing Tools.

In this scenario, if you choose the Rectangle option from that menu, it will create an outline around the area of the text that you select when you hover the mouse pointer over it.

Would you mind describing in a little more detail what actions or steps are you performing when you try to highlight text on that document?

Normally, you should be able to highlight portions of text by long-pressing the left button of your pointing device and keeping it pressed as you move it  across the word(s) that you want to highlight in a line of text or paragraph.

Then as you release the left button of your pointing device, the slected word(s) will remain temporarily highlighted in light-blue color (to indicate the selection made); right-clicking with your pointing device on that selection will pop up a context menu; selecting "Highlight" from that context menu will execute the desired action.

If that is what you are already doing, Is this happening on Microsoft Windows or macOS?

Also, assuming that the text that you are trying to highlight is the product of a scanned document, did you employed character recognition on that scanned page? (just curious)
