See > > > https://cygwin.com/cygwin-ug-net/using-specialnames.html#pathnames-specia= lchars Thanks for the excellent breakdown, Ken. Makes sense with the colon ":". Still not sure why it did work a couple months ago and now doesn't. I was under the assumption that 'cygstart' was a very basic program that just passed whatever it was passed on to Windows to handle - similar to "Start-Process" in Powershell, or well, just like double-clicking on something on the Desktop. My 'cygstart's last mod time is Nov 24, 2015 and this was definitely working *after* that time, so something else changed. It's like 'cygstart' is assuming this is a file and trying to do something smart that way rather than just letting Windows handle it (as it would *need* to do if this were indeed a Cygwin path). Again, when I add in the extra slashes, S4B *does* get the SIP request. Without the slashes, something in Cygwin is assuming this is a filesystem call. I'll take a look at the 'cygstart' code and see if (with my lowly programming skills) I can suggest a patch. :) --=20 Nem W Schlecht "Perl did the magic.
