Monarch Pro 9 ought to be able to handle the HTML document, but maybe there's something in there that's giving it a virtual headache.... :confused:
Try opening the HTML document in Notepad, and then saving it as a .txt file. Does that file work better? It might be a bit more challenging to work with, but it might be a workable solution. Just an idea.
Welcome to the forum, BTW.
HTML in Monarch can be a bit fiddly - Monarch reads the table structure of HTML to work out where the data is, but a lot of HTML generators use TD and TR tags to create whitespace for layout purposes. The result can be a pain...
I'd suggest getting a free XPS printer driver from Microsoft, depending on your OS, and using Monarch v10 Pro. Alternatively, print the HTML file to PDF from your favourite browser.
