I don’t think so.
I have a script with a timeout function after some seconds (they are considered part of the script itself, right? ). I launch the script from the tap function of an item, and I can have as much functions ‘waiting’ as I want (don’t know the limit if there is one)

I have set a script to positionchanged event and build a check if already an instance is running. If yes write something to logfile. This never happens

The position changed event is called when the previous one finish….I think.
Try to put it with timeout functions…maybe they work

Somehow setTimeout seems to be just ignored… Everything is done instantly

Well, depend on how are you checking it. I know some functions that returns the parameter they had when the script was launched, even if it is run minutes after with settimeout.
How are you checking it?

var doIt=function()
{
LL.setScriptTag(parseInt(LL.getScriptTag())-1);
LL.writeToLogFile(LL.getScriptTag()+”\n”,true);
}
var tag=LL.getScriptTag()||null;
if(tag==null){
LL.writeToLogFile(“start\n”,false);
tag=”0″;
}
LL.setScriptTag(parseInt(tag)+1);
LL.writeToLogFile(LL.getScriptTag()+”\n”,true);
setTimeout(doIt(),1000);

Hm, do it work if you launch it from a shortcut and you click it very fast?
Edit: the ‘or’ operator || in this sentence
Ll.getScriptTag() || default;
Is used to set a default value when the left part is null, so
LL.getScriptTag() || null;
Is exactly the same as
LL.getScriptTag()
😉

Wait a moment
Of course it is not doing the timeout, because it takes a function, not the output of a function.
I mean:
setTimeout(dolt(),1000)
is evaluating the dolt function, and then the setTimeout is doing the output: null
You need
setTimeout(dolt,1000)

Scripts are run sequentially, one at a time but can possibly be interleaved if one is paused (a dialog box).
When setting a timeout, the function is called later and holds a reference on local variables, hence it is safe.
There isn’t really a notion of instance of a script. Instead there are data (possibly shared through the root object) and there is code execution. Code execution is always sequential, but may be run partly.
