Hello,
LyX 1.1.5 and 1.1.6 both have this same, easily reproducible bug: if path to LyX file
contains spaces, one can't use View->DVI/PostScript/etc because of an error. If path
contains no spaces, the very same file can be viewed e.g. as DVI with no problems. I
must save my LyX files to /c/My Documents so I hit this often :(
Here's instructions how to reproduce this bug:
cd /tmp
mkdir "test dir"
lyx test.lyx
[answer Yes]
[type few letters to the new LyX document]
Select View->DVI - error!
If test.lyx is copied to /tmp, View->DVI works with no problems.
Best Regards, Tarmo.
