launch tFile with tApp

[Klaus major-k]

Hi friends,

macOS 10.3, LC 9.6.7

I have e.g. a MP3 file and want to open it with "Quicktime Player.app":
...
## tPrompt contains a localized string, of course
answer file tPrompt with specialfolderpath("apps") with type "|app|"
put it into tApp
## I select QTPLayer.app
if the result = "cancel" then
exit to top
end if
## tDatei holds the complete path to the MP3
## tApp the path to QTPlayer.app
launch tDatei with tApp
put the result
...

It will open the MP3 with QTPlayer as desired BUT
it also opens the file with "iTunes/Music" additionally!?
And I don't want that! :-D

The result is EMPTY.

Bug or feature?
And can I avoid to also open the file with "Music"?

Thanks in advance!


Best

Klaus
