Thank you for the quick answers.
My other Laptop has windows 11 (but 23H2) and uses the 7.1.3.0 version (the old GUI one) and it has no trouble with Grammarly. I guess the rich text component is not the same for both?!? (Also, there is no wordpad with that new windows 11 out of the box anymore 24H2, only on the older 23H2).
I will try to install the older 7.1.3.0 on the new computer and before explicitly activate wordpad on that windows 11 and report on the results. (But that will take at least until Tuesday.)
There was a second reason for inquiring for such function. I have an older backup laptop which has half sized DEL and INS keys above the single height double width enter key. About every five lines, I accidentally hit INS instead of enter and wreck accidentally havock. So a visual indicator of the insertion mode would be nice. One would think that if there is a way to show that one is on bold state, it should be possible to show the overwrite state. But after digging through the documentation, there seems no obvious way but to insert a letter and check if the size increases or not ...
Thank you
