Radius Dimension R (only)

Suddenly in SW2011, I can't easily apply the radius dimension R only, i.e. letter R without dimension, which is required when indicating a radius is full at the end of a feature whose width is dimensioned elsewhere.

Before this version I would delete the portion of the Dimension text, which would leave the R, but now the R gets deleted automatically.  If I try and type R it won't have it.  My work around is typing RR which then shows R, but I am suspicious that in future versions this might actually show up as RR on the drawing.

Does anyone know if there is a setting to disable the automatic deletion of the R when you have deleted the portion?
