Error running external command

[Tapio Tuovila]

Hi! First I must say that like much the LilyPondTool for jEdit, having 
used it for  several months now. Thanks for developers! That is great 
help for producing .ly files. Also lilypond itself is making great advance!

Well then: yesterday I updated to lily4jedit-devel 0.2.8-4 and 
LilyJHelp  2.6.0-1.
I'm using jEdit 4.2final on SuSE 9.3 with lilypond 2.7.3. Plain 
compiling of .ly files goes smoothly.

Now when trying to compile a .ly file with lily4jedit I get a message 
saying:
"Error  running external command. Please ensure that the path to 
bash.exe is set  up correctly in Plugins>Plugin Options>LilyTool "

Same happens if I try to convert-ly or if I type lilypond commands in 
the  lilypond console of jEdit. Think this problem is Cygwin-related, 
but I couldn't find a way  to correct it, not in LilyTool user manual 
nor in the Plugin Options of  LilyPondTool. So I'd appreciate your help; 
the new version of the plugin  seems promising!

Thanks in advance,
Tapio
