Thank you, Ron.
That command works but it is rather too drastic.
I have a new theory to test. Some pages are resistant intermittently to Intagging: I am not sure whether the difficulty is the number of target links that could be Intagged or some peculiar characteristic of the page. Anyway, this problem is recurrent.
I have my own HTML Internet Home Page which lists 277 links (bookmarks) within a table (with at least 277 cells). I think that it is possible that Voicecomputer is having difficulty intermittently in populating that with Intags.
For experimentation, I have set my Opening Page to the site called Duck Duck Go: https://duckduckgo.com/
The Home Page is different from the Opening Page.
Duck Duck Go is selected because it attracts only seven Intags and responds easily to the "Intag it" / "Show numbers" commands. If I call up my Home Page (the one with 277 links) subsequent to Duck Duck Go then it appears to populate with Intags without issue; i.e. once the first-page is populated with Intags, subsequent pages irrespective of size populate without issue.
I need to test this during the coming week to see whether it resolves my problem.
