Build 8.0.18494 on Mac 10.7.5 Join.me and coherence Black Screen of Death

Good evening,

Has anyone else experience a mac Black screen of death while running Coherence and Join.me?

I often have Win 7 guest running and have someone (usually some product support person) Join.me to my mac. When both are in play it seems to inevitably leads to the BSOD.

Thanks.
