Hi all, I wanted to follow up this thread in case anyone else has the same issue. The temporary solution I have found is to: (1) in LyX, do File > Export > LaTeX (plain) (2) in SWP, do File > Import Contents
This appears to import the LaTeX code within the begin/end{document}. This seems to work for a document with text, mathematical equations, and floats but it does NOT like tables. When the document has a table SWP utilizes 100% of the CPU and the memory usage climbs continuously. I'll update this thread if/when I discover more. Ken
