Thank you for your response. I did find out the following:
Starting in Dynamics SL 7.0 and for all later versions the AutoSave customization functionality is turned on in the Solomon.ini file in a section resembling the following:
[Miscellaneous]
SaveSettingOnExit=XXXX
Where XXXX is either YES or NO. If you want to ensure that this functionality is off for all users in 2011, set the value to NO in the global Solomon.ini file.
To remove the unwanted Auto Saved customization, you can run the following statement:
Delete from customvba where description = 'Auto-Saved Customization'
