The original Quark 4 document, opened in Quark 9, looks fine.
I saved it as a Quark 9 document, then reopened it in Quark 9, and it looks fine.
I opened the Quark 9 document in Quark 10 and it has the same problems as when run through the Document Converter -- images with red backgrounds, images that no longer fit their picture boxes, etc.
So, it appears the problem is with Quark 10; it can't properly display a Quark 9 document that was saved from an original Quark 4 document.
That is going to be a massive problem.
We support dozens of customer who have been thousands and thousands of Quark documents in Quark 4 through 8, as well as 9 and 10.
We told them all the buy at least one copy of Quark 9 before it cease to be available, so that if they ever wanted to upgrade to Quark 10 or higher, we could open their 4-8 documents, save them as Quark 9 documents, then be able to open the Quark 9 documents in Quark 10.
But based on what I am seeing, that is not going to work to any acceptable degree.
