Sorry I didn't see this post until now.
Can you try with the latest 220.127.116.114 build available for public download? Many stability fixes have gone into it.
Does it happen randomly or you're able to reproduce it at will.
If it still crashes using build 18.104.22.1684, i'll mail you a debug build right away to help root cause it.
Moved to the new Raptor Group.
To continue with this thread customers will need to join the group first.
