[Dual Monitors and MAME opening up on the wrong monitor.]

OK, I don't know what the issue was, but I deleted my display drivers, unplugged the 2nd monitor, shut down and restarted and mame now loads on the correct monitor. 

[Dual Monitors and MAME opening up on the wrong monitor.]

Sorry to res this thread, but I am having a simular issue.

I have 2 monitors (a marquee screen and game screen), I found the displays by using the verbose command. I edited the .ini file but it doesn't change anything. 

In my display properties it lists the monitor I want to display the game on as screen 1. But both mame and BigBox see it as screen 2.

I am editing the mame.ini file in the main mame diretory with exe file. 

Any ideas?
