Many instructions in Quattro Pro Help are complicated, and I would like to be able to toggle back and forth between a spreadsheet and Help until my problem has been solved. That was also a problem with WP9, from which I just upgraded to WP21, and it is distressing that this problem hasn't been corrected since then. Due to this problem, I have to copy the instructions from Help into a document and toggle back and forth between it and the spreadsheet.
I don't have any problems with the QP 2021 help window on Windows 7.
You might try an online copy of the help file or the PDF manuals (via Help - Reference Center).
