Objects and Screen Jump Around

I'm using Captivate 10.0.1.285   on Mac High Sierra.

I'm workington a slide presentation with drag and drop activities.

When I zoom in on my screen to work on specific elements at the bottom of the screen, every time I click anything the screen jumps back to the top.  Then I have to scroll back down to the object that is now off the screen. 

For Example:  If I want to click on several items to group them or to move them, each time I click on an item, the screen jumps back to the top.  I then have to scroll back down to click the next object that is now off the screen.  I click on that item, and it jumps, and I have to scroll.... over and over.

Also,  if I click on an object, the object will jump to a new offset position on the screen.  I then have to hit "undo offset position" before I can carry on with what I want to do.

If I am in the drag and drop wizard, and click on an object, if it jumps, I can't undo the jump, and have to remember to realign everything after I finish the wizard.

Can anyone help?

Thank you.
