"Account" settings are not retained by the application. They are stored with each file. There is a known issue with the windows menu on Windows systems where the windows menu fails to list all files that are open so this is not a perfect test for which files are still open, unfortunately. Thus, the file may still be open even though it is not listed.
thanks phil.... after tinkering with this for a bit, i discovered that if i insert a "close file" script step (a step i was previously unaware of... i kept looking for window related steps that would find or close the "hidden" windows) into the closing script for the user interface and specify the data file, then it took care of the problem. i should have spent a little more time tinkering... sorry for being so lazy!
