Designer Interface - Separate Windows

[JoeFine]

Greetings....

Don't you just hate when last night you closed an application, and all was perfect... then overnight some computer who-knows-what happens and you reopen your application to find everything has changed?

 

Somehow this morning, my design interface is all separate windows.

I have looked and tried several different menu options, but can not find the right one. How do I put the interface back to one solid screen?
Thanks in advance.

Untick Window > Separated Mode …

Hi JoeFine

Goto the Window menu at the top of the screen and click on the separated mode and this will return the app to a single screen

Oh for pete's sake.... out of 15 things I did try, I totally missed that one.... duh.

Thanks kindly.
