SW06 SP5.1 Ordinate Dims Problem

Running SW 2006  PS 5.1... On a detail view, I used tobe ableto force ordinate dimensions, by selecting "OverrideValue"and simply adding to the existing value. (e.g., Wherethe initialvalue would be 0, I would type in "+32.685"for example, and thedisplayed value would be 32.685.  Thenext ordinate dimensionmight be 4.21, and I would again type"+32.685" behind the currentvalue and let SolidWorks dothe math, displaying 36.895.)  Now,the override value featuretreats the box as a text string,displaying "4.21+32.684"(for this example).  I'm not sure ifthis happened with theinstallation of SP5.1, or if it happenedearlier.  Has anyoneseen this, and is there a workaround/fixfor this problem?SolidworksDrawings And Detailing
