Hey'up Allura,
What I've found so far is that 2 of the basic elements, fire and water, don't seem to have a problem working. I made a shower with a script (lifelike water, no dots,lol) and it worked straight away, until you link the on/off buttons then it don't work, but I think that's due to the link set bug.
Also, a beer/coffee drinking script works but other drinking scripts, such as the gun script from sl don't work.
Basic sliding door scripts seem to work. I've also seen some particle scripts working in fountains etc as well as the sound of rushing or flowing water.
I have a curtain script which works for a while but then the whole prim goes up and down.
Cheers....Legs Lover.
