Hello,
I want to use KMPlayer for playing my mp3 files. But with every click in dolphin to a new mp3-file starts a new session from KMPlayer, so there will be more and more KMPlayers on the desktop.
I don’t want to use or need a playlist into KMPlayer. I will start every mp3 to exercise with my guitar-playing.
Do you have a hint for me?
Thank you very much
regards

Hello,
Have you tried to go to Preferences window navigate to General tab (on the right pane) and uncheck the box reading Disallow multiple instances ?
For some reason KMPlayers is seg faulting on my end and crashing when i try to go to settings (not using it usually), but i prefer SMPlayer as front end for MPlayer … and is running just one instance … Maybe somebody else has a clue or speaks german and can identify things from your screenshot. 
Thank you for your information, @anon89812132.
I use SMPlayer on my other computers and it works very well. I would like to prefer it, but here I have a brandnew manjaro-kde-installation on my new tuxedo - laptop. Here works SMPlayer very unstable and it freezes every time. KMPlayer works fine here.

same thing here - as I tried to have a look and installed it to a Manjaro VM
It crashes as soon as I open the settings.
I do speak/read german - in that screenshot there is no setting to allow just one instance.
Not in that tab that is shown anyway.
Hello @anon33601770 ,
I searched into all tabs but there is no setting to allow just one instance.
So I see no solution for me, but it is not a big problem for me.
Thank you very much for your support, @anon89812132 and @anon33601770

… well
perhaps the file manager is not the right tool for the job that you want to do? 
perhaps a suitable audio player - and a custom playlist which you can control via it’s interface is …?
I was basically just translating the meaning of the items that are visible in the screenshot - and relaying that.
Cheers!
