Thanks for your assistance Ken. I appreciate your time. Unfortunately it didn't seem to do the trick for me.

I added your code to a mdule of its own, and set your macro to run after big pastes, and before saves in my code. I've tried both alternatives seperately, and in combination, but unfortunately I'm still receiving that error message.

Strangely enough, I turned on my task manager and clicked on "Performance" to view the free memorey and CPU usage, and then ran my macro. It seems to be perfectly fine, and doesn't report back high memory usage. I've tried running it on other computers and have still the same problem. Resource availability appears fine, yet I still get the message.

Grrrrr....
