I made my forms modeless and that seemed to help.

I put test code in the click button after the show call:

frmCNA.show
messagebox('after show')

This didnt execute before, and now it does. Fox must run all the code in the click button and return (which means it wont try to go back there later and continue execution). After I click, the new form is active and all is well.

I don't want modeless behavior... but all my forms are the same size, so the user cannot switch unless they use my buttons.

Any further commentary is still welcome.
