With the new registry module you can grab the values of each of the cursors selected by the user, and assign the appropriate one to your label. That ought to allow you to get the kind of behavior you desire. The relevant registry keys are here:

HKEY_CURRENT_USER\Control Panel\Cursors

There *are* five different size cursors though (SizeAll, SizeNESW , SizeNS, SizeNWSE, SizeWE), so you'll need to decide which one is appropriate. The rest is left as an exercise for the reader.
