Hi Stephen
Well, I think it is because the cygwin sh.exe and the msys sh.exe
are not the same. I probably mentioned that earlier when I suggested
taking Cygwin out of the windows Path. sed.exe can be a problem.
But this way can work but takes more effort. To start with something
easy, let us try pdflatex. Do you have Acrobat Reader installed?
Then go to Tools->Preferences->left-click on File formats and then
scroll down to PDF (pdflatex) in the window that opens to the right.
In Viewer: which is to the right, type in acrord32, Apply and Save
Close LyX and then open. I think you will have a pdflatex viewer.
Maybe you might have to Reconfigure, which is also under Tools.
Close LyX and reopen.
I did the test with Acrobat Reader (it was not autoconfigured) and it
did not work. I checked the paths shown in lyxrc.defaults and set them
to the correct locations (it seems that there is still a problem in the
configuration). Another test started Acrobat and loaded the file
correctly - yeah !!!.
The next test was of course to use dvi viewer yap. There I got again the
python message and a backtrace on the shell. I mentioned that I had
removed dv2dt.exe and dt2dv.exe from the bin directory too (when I
removed all the msys files). After copying them back from the backup yap
started as well.
So I have to thank you a lot for your help and the tips you gave me.
Now I can start working with lyx :-))))
And I'm sure I'll enjoy it vey much

PS: Nevertheless I'll try the new_msys-1.0.dll too and give you a
feedback on that matter
