Problem with Corona scatters

When I have corona scatter in scene, and I try to create anything object it works some longer
When I hide all corona scatters and try to create something, max work normal.
Is it Normal?

Hi, which version of Corona is that?

As far as I understand Max becomes slow when you are using CSCatter + any other object, is that correct?

Is this happening even with “empty” CSCatter objects, or only if something is actually scattered?

yes.
I always wait about 2-3-5 minutes to add distribute object or change random seed.
Coronascatter works bad in 1.4

Have you tried if the same thing happens in the daily builds?
