Only able to run 1 AOB per game?

I've been running into this same problem with a couple of games recently on Firefox.
I am able to find the address after searching for the AOB provided, but I can only find 1 AOB address every time I refresh, is this normal?

Let's say I search for "infinite money" AOB, I find it and change it, I search for "infinite health" AOB, I can't find it.
But if I refresh and search for "infinite health" AOB, I can find it and next I search for "infinite money" AOB I can't find it.
I can run both of them, just not concurrently.

not enough informations. Which games? Is this a khut problem? Provide screenshots if they help. System informations might help too 

All the games I've tried. So far, that includes:

Hippolyta
Rogue Soul 2
Tower of Greed
Bloons Tower Defense 4
The Necronomicon

Might be to do with the Cheat Engine I'm using, it's i386 and I'm running it on Mac.





Thank you for taking your time

There's a quick solution for this.  Stop using a Mac.

Yup the OS is the problem. You might want to check out the official trainer topic http://gcw.cz/trainer
