That was it. Something in my code was calling for the form to be Refreshed, at which point it started trying to work with Fingoods again. I simply left the "select fingoods" line at the top of that code and all is well.

I never realized that simply closing a browse window would cause the Activate code to run on the window below.

Thanks very much to everyone for their help on this!
