Label seems to be adding leading spaces to string

Hi folks,

When i put a piece of text in a label control, it seems like there is a misalignment of the first row of text only., i.e. if the text in the label overflows one line it looks like you have indented the first line: 

The label is just rendering as a span.  If i use a public var and just use <%=CalcMSG %> it aligns correctly as you can see above.

Is there a reason for this?
