The WMF files produced by Corel Draw X6 16.4.1.1281 are no longer valid.
WMF File format has always worked until this point.
The only suggestion for anyone affected that I can see is to downgrade.
Has anyone checked WMF file format output is functional (and tried to load resulting WMF file into something else that reads WMF) in the new Corel Draw X7?

That is a very good example, and by adding colour to the various paths I can see exactly what the problem is:
When CorelDraw creates the WMF, it is closing open paths and hence creating the extra lines.
I will document it and pass it to Corel for investigation, but it will probably take a few months to fix.
What are you intending to do with the WMF file when you have exported it? If it is to paste into MSword or openoffice, maybe you could create EMF or WMF instead -- these seem not to have the same problem.
