Can someone test Windows source view?

[Richard Shann]

If someone who is running the latest version (post 7th November anyway)
of Denemo on Windows 10 could test that the 
Open->Open Source for Transcribing
command does successfully open and display a PDF file I'd be grateful.
A user has reported seeing only the window on the taskbar but it won't
display...
This is rather blocking the release now. (Oh, and apologies for the
build for windows breaking for a few days, it is now being built
successfully on Debian 11).
