As far as I can tell, all buffering is off. It's turned off in the Tools-Options and in the DE for all the forms in the whole project. Just for giggles, I tossed in a FLUSH button and clicked it often while navigating around in the form and it still crashed when I tried to close the form.. It actually took me a try or two to get into the program. It crashed after only switching records once and caught me by surprise.. I guess it's time to reboot again.. Also, no changes are made to any records in the table when/before it crashes. All I'm doing is navigating around. Essentially, changing records on the main table like this:

Vendor: Filter to costumes, sizes, accessories
Costumes: Filter to assigned accessories, sizes, colors. Also a number of cursors associated with record changes in the costumes table. 2 Selects and a number of requeries for each record change.

I'm scrolling through a listbox for the vendor table, which in turn updates costumes which in turn updates those other selects and relationships. No changes are made to anything, unless clicking in and out of a field would be considered changing? What else would cause fox to buffer the table data?
