In Access 97 under Windows XP under Virtual PC on an OS 10.4.10 Mac, some Control Tips show up when the pointer hovers over label boxes associated with list boxes in a form, but other Control Tips don't. I've tried binging label boxes to front, moving them to remote locations on forms, creating the controls by draging fields from the field list, and creating the controls using the tool box 'wizards'. So far, the problem has not arisen for check boxes.
