Nope, that's what ObscureCursor is for.

ShieldCursor is used to hide the cursor in case it might interfere with
somthing going on with the screen.  For example, all QuickDraw operations
involving the screen call ShieldCursor with the bounding box of the graphics operation.

The only time you would call ShieldCursor yourself is if you were
reading/writing the screen directly without using QuickDraw, which is
usually not a good idea.
