having 4 screens : how to control splashscreen to start in center of 1 of the screens ?

"centerscreen" or "centerowner" doesnt work .

And how to control that the splashscreen and nextcoming userform will start in the same window from where you started the excel file? (sometimes when i run the excel file the splashscreen is showing at one screen and the nextcoming userform is popping up at another screen)

Any ideas?
