with the latest monkey tester I see that updating the stylesheet does not update the showingDelay property immediately.  When the tooltip gets shown, I see the following output from the change listener added to this property:


showDelay=1000.0 ms
showDelay=100.0 ms


I suppose the second setting of 100ms (the value I actually set) happens too late or simply is ignored.
