Hi.
I have taught several newbies. I always start with a simple app, like an
address book. I show how controls are created, and how scripts are built.
During that process, I am off in the weeds, writing short handlers showing how

It is possible you have not placed a blinking cursor into the inspector field?

That works here as advertized, no formatted text after using the shortcut or

Thanks for the followup on this. I experimented some with tesseract and
came to the same conclusion.
Since the values assigned to each character are standard wthin Scrabble,
I don't really need to detect those tiny numerals. But the alpha chars
are of course essential.

You need some criteria to find the topleft of the grid and the

After a second read I think it will be hard to find a service to do that

Indeed it does.
I *am* truly fascinated that for once, I’m the one not having problems while
others are being terrorized by the dreaded Pirate Code Dots . . . .
They sill move around the script in odd ways at times, but the ones that stay

Klaus.
Now I see what you see. I cannot be sure I did not mess up the procedure
earlier because I am getting mixed results. Sometimes the paste is formatted,
and sometimes not. . But now when using the menu, if the formatting is indeed
plain, nothing appears in the card field.
