Lax,
Are you taking a peek at your new function or waiting for a simple macro to demonstrably reproduce the crash bug? I can probably extract some essense of my RH macro to help generate the problem, but I won't bother if you already have enough empirical data from the other posts to look into it.
Let me know if you need it, and I'll see if I can provide a test case to kill FastCalculate().
Thanks
