I'm running Sandboxie 4.02, EMET 4.0, and Firefox 22 with flash updated to whatever the latest is. EMET is using the "Popular Programs" configuration. I listen to a lot of music on Youtube and once a day (or every other day), I get a notification from EMET saying it detected a Heapspray mitigation from flash and closes flash player. If I refresh the page it might happen one or two more times before the video loads. I'm assuming there's an incompatibility here; I doubt someone is attempting to attack my computer daily(if they are, they aren't succeeding ). Is anyone else having any issues like this?
