Order of selecting objects

When individually selecting objects which are on top of eachother, AutoCAD seems to default to an object created earlier than the latest one. However, on a colleagues CAD station the last entity created is the one selected. I know I can hold down the control key and cycle through the entities to select but its annoying! Is there a system variable that controls this behaviour? TIA

Check the SORTENTS variable. Tools -> Options -> User preferences -> Object Sorting Methods.

However,

Does SORTENT control object selection as well as for plotting?

Type in "Preferences."
In the dialog box, pick the "User Preferences" tab.
The rest is self-explanatory.
