I made a circle sprites and added “Draggable by mouse” automatism to them, but it doesn’t work - during the preview I cannot drag this circles by mouse. Why?
I added the event that when mouse cursor is on a circle and left button pressed activate automatism “Draggable by mouse” but still it’s not working. 
Can you post a screenshot of your event or upload your file?
I think you should left the automatism activated because it already manage the mouse clicks.
Do not disable the automatism. Everything is handled by the automatism itself 
I tried with no conditions to activate the automatism but nothing changed.

Then I made another project - added coin sprite, added automatism “Draggable by mouse”, and without any events I can drag it with mouse during the preview.

What I’m doing wrong in the first example? 
I suspect this is a bug.
- I recreated the project. First I added a circle sprite and made it draggable by mouse. It worked.
- Then I added a board (panel sprite) and copies of the circle sprite. It still worked fine. In the preview I could move any of the circles by mouse.
- Then I added an event: “when there is 37 circles, the cursor is on a circle and left button pressed destroy the circle”. It should remove the first circle and others I still shall be able to drag. But after removing one circle I was not able to drag others.
- OK, I removed the event I was just created, but I still can not drag the circles anymore.
