typing glitches in Windows Mail

[VINOSABE]

annoying recent development...after composing an email, if I go back /click /
move cursor to insert a word or a punctuation (NOT highlighting anything),
often (but now always) the new word I am entering "gobbles" the text already
written that follows on that line, letter by letter, space by space,
character by character...
If I type in a 5 letter word, the next five letters or spaces disappear; a
seven letter word with a comma at the end will "gobble up" the next 8
characters....
Is there some option or keystroke that causes this, or can stop this from
happening ?

Click the Insert key. It toggles between destructive insert and
additive insert modes.

Destructive insert is often called overtype.

o.k. thanks !
so now I have a way to fix this annoyance...
I'd like to know how to prevent it in the first place...
any idea why my computer jumps into the "destructive insert" mode, seemingly

Most likely you have hit the Insert key by mistake, typo-ed. I have a new
PC and the keyboard layout is a little different and I have to click it
every now and then because I've hit it by mistake. It's not a big deal
really, if I start over-typing instead of inserting, I know to hit Insert .
.. . . .

If it happens again and you are totally sure you did not press the insert
key, it is likely a defective keyboard.
