[quote="L1ttl3J1m"]It's happening again but further along in the game.[/quote] It only happened once - Trying to make it happen again now. Actually, :oops: my IDsDriverBufferImpl_SetVolumePan errors are at the very beginning of the game, but not when the symptom I'm having happens. Sorry, it's probably not all that related then. Although bypassing the wbemproxy.dll does reduce the problem I'm having to a random intermittent bug.
