How to move pop up windows?

I assume I’m going to have a permanent pop up asking me about source content files until I can get a good answer on how to go about that issue. This wouldn’t be the biggest deal if it weren’t for the fact that it is permanently blocking other pop up windows such as the building lighting one, and the other issue is that when you have a pop up on the screen it is constantly freezing the editor and coming to the forefront to gain control of the cursor, this makes typing within the editor extremely annoying.
Also, if I dismiss the new detected content files popup, will I be able to redetect said content somehow again in the future? Any suggestions would be appreciated thank you.

I’d still like to know how to move these windows, if possible. Thanks!
