As a novice this is difficult for me to review.
Firstly it loads and prepares itself quite well. Then it confuses the commands ;-
( ctrl and C AND/ OR ctrl and V ) neither of these actions work initially.
Only after four or five attempts it may paste . usually I have to restart the whole procedure.
Next, why must we have control and C or V ? surely to paste is easier.
After that I find that one can’t justify the print or change the font and/or font size?
I have a lot of MS word that I have to be copied and pasted. After half an hour its frustrating .
Anyway I don’t mean to demean you or your efforts and I admire the fact that you have written a useful programme that may need tweaking.
Lastly when I attempted to start your review my lap crashed and restarted its self???
That’s a first.
