Stop Multiple Instances in Kubuntu 12.04.1

[anirbanghosh]

How can I stop launching multiple instances of same program in Kubuntu 12.04.1.
For instance, if I am playing some song in VLC and in due course of playing if I click
another song, again a new VLC window opens up and starts playing simultaneously
two songs. How can I stop these issue?

Thanks but how can I do for other applications also such as Dragon Player.
I did not have this issue ever with Ubuntu ever. But this is strange in Kubuntu.

Dragon player is meant to be a simple video player. If you have VLC, there is little to no reason to also use dragon player.

As far as I could tell, dragon player version 4.10 and newer support single-instance-application. Check your version number on Kubuntu 12.04.1, as your version of DP may not have an option for single instances.

Thanks cc7gir, to be honest I don't use either of these applications.
