What's the trick to disable an object tooltip?

 

Programmatically placed arrow objects work but interfere in readying the chart.

The common function below, in hopes to disabled it, can't handle dismissing it.

ObjectSetString(0,sName,OBJPROP_TOOLTIP,"");

In the object you drawn manually for example, this is what you see,.

I have indeed seen that it's possible, I just have no recollection of it.

 
ObjectSetString(0,sName,OBJPROP_TOOLTIP,"\n");
 
Is there a way to disable tooltips programwide? While they are informative in first 3 minutes of use of the program, they become annoying and detrimental over time. There is a number of tricks user has to elaborate to avoid tooltips covering the information the user looks for when hovering mouse over an object or using crosshair tool.
