Back Again - think I clearly identified my issue...

[duloz]

Alright, so after my post yesterday, I discovered that another feature outside of GameEx that I wanted to get working was not possible in Windows 8... I had windows 8 Pro installed, so it was easier than not to downgrade to Windows 7 without touching anything, except that I had to reinstall GameEx over itseld in order to re-register...

And suddenly: Mame roms are once again not showing up....

I realized that the only major difference between my arcade cabinet, where I was hooked up during this work, and at my in-laws where i got gameex to find all of my roms: my cabinet has a touch screen.

I just turned off touch features in GameEx config, and it seems like the rom detection is taking the longer amount of time that I experienced when it started working correctly yesterday...

May be somethign to add to the obvious list of culprits as the number of touch screen laptops increases.

That's good to knoiw, thank you for following up with your findings. It will most certainly be something to keep an eye out for.

It would appear you have in fact discovered something. Disabling touchscreen resolved Brandonjmusic's issue as well

I believe I actually brought up the touch screen function messing with my setup as well at some point. It may need to be something for Tom to look at.
