If a hyperlink is in a textbox the right click menu does not appear.
Occasionally I copy and paste a text box to another page, so I can keep the formatting and location of the text. However, if the original textbox has a hyperlink in it, and I select all the text to replace it with the intent of using the right-click menu option Paste Unformatted Text, the menu does not appear. And will not for that textbox ever again. This menu does not appear for any textboxes with hyperlinks.
I can’t paste text (neither unformatted or formatted) when right-clicking while the mouse is over a hyperlink although I can if the mouse is over a different part of the textfield. Still the context menu opens any case.
Pasting a hyperlink unformatted will remove the hyperlink…
Maybe you can try to paste the text formatted. You could also try to paste the text unformatted not via the context menu but with the shortcut: [Ctrl] + [Shift] + [v] That worked for me even while the mouse was over the link.
