This is because the proper environment is not set. In order to launch
LyX through the Windows GUI, you need a wrapper. Please compile the
attached C source file, put the attached lyxprofile file in /etc and then
create a shortcut to lyx-win.exe. When you launch LyX through this
wrapper, everything should work Ok. You have to set the HOME environment
variable in Windows (use the Windows style, it will be translated to
posix style by the cygwin dll), but otherwise you should not do anything
else. This is also how the cygwin package I provide works.

Well, I think it is already fully supported in trunk and partially
supported in branch (where the SumatraPDF.sh script should be used).

Yep.

I think that it could be supported through the named pipe mechanism,
but nobody until now has provided code for doing that.
