Hi,
i set music file types to open in a wave editor when opened via ctrl-doubleklick (normal klick opens winamp), which works ok
(file types -> mp3 -> edit -> events -> left double klick ctrl -> edit -> \program path\ %1), except when the files are containing a "_" character, then causing the application to hang.
which application hangs? Opus or your Wave Editor?
the wav application is hanging. I have to correct it, though. It doesn´t depend on the "_" characters. What is happening, the editor is displaying something like "opening x x" or "opening x x x", where "x" is a square symbol.
It seems to be the blanks in filenames, which are causing the trouble. It can easily worked around by using "open with", which is working correctly. I don´t know, if this is a bug, but maybe worth to be looked at (probably applying to all applications opened in a similar way). What happened to the "edit" function in this forum, anyway? 
Place "" characters around your function argument so that the filename/path with spaces is enclosed in ".
thx a lot, now it´s opening properly.
