Framemaker 2017 - Print settings keep resetting default printer to "WebWorks Rasterizer"

Since we installed Framemaker 2017 (Tech Comm suite, actually) we keep running in to issues where long standing books, on PCs with the default printer set as Acrobat Distiller, keep somehow changing to "Web Works Rasterizer" when we go to create PDFs.  Seems to be more common after a crash, but it is behavior none of us have seen before.  We've also got a maybe/maybe not issue with printing to PDFs using print to a .PS and distill where there is a  "hanging" pixel that appears after auto-text with an overline style applied.

Is our network haunted or is anyone else seen odd or unexpected behaviors on files with Frame 2017?  Overall with this tech suite we seem to keep running in to issues where things have worked perfectly fine for 10 years and now little issues all over the place.

Thanks!
