Since then, I've found that doing a RefreshGList on a just deselected gadget
is what causes the problems (It seems to think that the gadget is still active
and displays a cursor). I've found (Prepare ASBESTOS suit) that the following
will 'cure' this (and the 2nd) problem (ASBESTOS suit now being worn):

IntuitionBase->ActiveGadget = NULL;

Any better workaround, or comments ?
