Thank you both for your thoughtful suggestions.

I think you're probably right, Diolma, it's most likely a memory fragmentation problem. After all, we've been dealing with that issue on PC's since the beginning, haven't we . . .

Maybe I'll pickup a ram de-fragger and run it periodically to see if that helps. Meantime, it's not that big of a deal to shut down the program occasionally and re-launch it. I just thought maybe there was a tweak I was not aware of that might help.

Cheers,

R.
