Turn off annoying popups - How to, and please!

Surely there is an answer for this? How do we turn these off? I shouldn't have to stop what I am doing, find the tiny itty-bitty x and click it, and then return to what I am doing. Whoever thought it was helpful was wrong, wrong, wrong. I see a brief conversation earlier where the person was given instructions on how to do this in Photoshop, but those options don't apply in Dreamweaver. And that was the end of it. Heck, I even clicked the "I know what the heck I'm doing" option when I updated Dreamweaver.  I shudder to think what I would be seeing if I had clicked the "I'm a newbie" box!
