In my opinion, go to "Selector Properties - General page" and choose "2D/3D Depending...", then stay away from the "Toggle" switch. There's a good possibility that something might be 3D, though you'll never know with the 2D override turned on. With "2D/3D Depending" turned on, TurboCAD will show you if your selection is 2D or 3D; XY or XYZ handles and the different fields in the Inspector Bar. Moving 2D and 3D objects together will usually create workplane problems; move them separately.
Upgrading won't make a bit of difference, though there may be some newer 2D tools.
My two cents.
