Re: [Denemo-devel] Release 0.8.16 - Gub Status

[Richard Shann]

I have found a fix for the bug!
In the executables there is a lilypond-windows.bat.in and from that I
gather we need to add a -dgui to the command line
I have succeeded by invoking lilypond-windows via a batch file that does
this (changing the denemo pref to point to the batch file that adds the
-dgui parameter).
I'll try to check in later, and withdraw the mods to print.c except the
export pdf which is broken anyway.
