Okay, thank you very much for your help and input.

I'm currently using the freeware version (a few months old) and Mame 0.241. I also tried deleting all lines under autohotkey, no luck.

I may not have worded my problem the best. Mame isn't auto launching multiple times when I select a game. The issue is, if accidentally pressing the launch button more than once on a game (which my kids do a lot) multiple instances of Mame launch. Another topic posted something similar a while back and it seems to fix the problem, but it was a feature in a beta release. Which may be in a proper release now, I'm not sure. I'm currently using the freeware ver at the moment.

I'm running launchbox as my front end with Mame 0.241 as my only system installed. However, if someone selects a game and accidently presses the launch button more than once, Mame will launch multiple times. Is there any way to prevent this? Thanks
