>CLOSE DATA only shuts the currently SET dbc. CLOSE DATA ALL usually shuts all dbcs and contained tables, but occasionally I've had to issue a CLEAR ALL to really get everything closed...

I've had to do a CLOSE ALL in the same situation to make sure that the dbc is really closed. Closing the database from Project Manager always works, but CLOSE DATA definitely does not, and it's irritating. I mentioned this in my article on VSS in the Oct 97 FPA.
