BASIC dimension display problem (dual dimensions)

I've been experiencing a problem with the display ofdualdimensions when using the Basic tolerance style.  Theboxaround the dimension is split - there's a box around theprimarydimension value and a separate box around the alternatedimensionvalue.  The box should surround both values at once. Ihave seen it displayed that way on some drawings I createdin thepast, but for some reason I can't find the reason for the wayit iscurrently displaying.  Anyone got an idea what might begoingon?SolidworksDrawings And Detailing
