1/3 of my D3 usually crash once in a 24h period using 246. D3 screen stays open but in a frozen state, until I manually close it, then the error msg. Sometimes the DB attached to it will auto close with D3.
The error isn't always the same... but the end result is my D3 window freezes mid-action. Nothing moves, controls don't work. I have to ctrl-alt-del and use the task manager to kill D3.
