Check Document Scope and Update Software

Determine if the bug is isolated to a single corrupted file and ensure your Acrobat application is fully updated to resolve known glitches.

1
Test multiple files

Open a completely different PDF file in Acrobat Pro DC and test the commenting tools. If they work normally, the original PDF may be corrupted or incorrectly formatted.

2
Check for updates

Navigate to 'Help' in the top menu bar and select 'Check for Updates' to scan for newer versions of Adobe Acrobat.

3
Apply updates

Install any available updates, restart the Acrobat application, and attempt to use the strikethrough tool again.

Frequently Asked Questions

Why does my cursor turn into a plus sign in Adobe Acrobat?

A plus sign cursor often means you are in a different selection mode or that the PDF consists of scanned images rather than selectable text. Running OCR (Optical Character Recognition) on the file can convert images to selectable text.

Are PDF comments saved in WPS Office compatible with Adobe Acrobat?

Yes. Any highlights, strikethroughs, or text notes you add using WPS Office conform strictly to universal PDF standards, ensuring full visibility and compatibility when the file is opened in Adobe Acrobat or other PDF viewers.

How can I tell if a PDF has commenting restricted?

Open the PDF, go to 'File' > 'Properties', and click the 'Security' tab. Review the 'Document Restrictions Summary' to confirm whether the 'Commenting' status is listed as 'Allowed' or 'Not Allowed'.
