Hi Jim
Only just had this post pointed out to me.
The logs probably contain security access issues. GP Power Tools has the option to stop logging of security issues to the log files so they will no longer be created unless you have other features enabled that write log entries.
Note: MBS_Debug_Mode=TRUE is used to enable the Advanced Mode features so they appear on the menus of the Support Debugging Tool.
This dex.ini setting is no longer used in GP Power Tools as all features are visible (as long as security access to the windows is granted).
