Hi Michael,

I attached the trace log which has actions: open the file coxph_bench.r,
and edit it, and save it. If you need the full log, please let me know.


Occur: c:/\|drive my help.

Looks like something of "| | | | | | 7 -> (tramp-drop-volume-letter
"c:/opt/home/username/test/coxph_bench.r")" was not applied.
