Hi mir4ea, because the delete involves modifying geometry and not just altering selection states, it needs to be run in a slightly different way - instead of an "inline script" it needs to be a command.

I've attached a command script that will do this function, to use it copy the attached file into the \commands sub-folder inside of MoI's main installation folder, then that will make a new command available named SelectOuterLoopsAndDelete. To trigger the command set up a shortcut key and put in the command name which is SelectOuterLoopsAndDelete (note - put in just the plain command name SelectOuterLoopsAndDelete , no extra "script:" at the front, no ".js" at the end).
