How to get rid ot fog/mist maker?

I tried the "mist maker" (or fog maker?) from my inventory "free particles/glowies" und put it unfortunately on my floor. But how to get rid of this? I cannot stop it..

I use the linux Client.

Hi, Burkhard - angle your view so you are looking straight down* on the particles. Draw a big yellow edit box and it should take in the mist box, which is transparent - you'll see an outline (or even just right click where the box should be - you'll probably get it). Check to make sure you have just one prim - the right prim - selected, then delete it.

If you turn off** particles, highlighting transparent can work, too - but if you leave particles on you won't see much.

*so you don't select a million things
**or just greatly reduce particles seen in preferences

Was this an object you dropped onto your floor or an actual script?

If it's a script, simply removing it won't be quite enough, as the particles become a persistent property of the prim once started. To get rid of them,

Edit the floor prim where the particles are coming from, and go to the content tab - you should see the script you dropped in there. Delete it.

Then, create a new script on that same prim that looks like this:

default
{
	state_entry()
	{
		llParticleSystem([]);
	}
}

You might have to reset the script to make it work, but that should stop the particles.

The particles are not coming from the ground, I removed the floor completely, but cannot see the object which is responsable for the particles.

Thanks a lot, Therian solved the problem...
