Reier he precisely stated that he was using ctrl or shift => NOT selecting AP's.
Craaig, i may say the obvious and you might now that already, but here is what you must do to use shift and ctrl to rotate a component:
-Select component and attachment point.
-Hover it on your baseplate and use Ctrl/Shift BEFORE you attach it.
-Attach it.
If it doesn't works, your RA2 is probably messed up...
