There appears to be some form of precision issue with the starting value. The following work on my system:

$Version

"7.0 for Mac OS X x86 (64-bit) (February 19, 2009)"

Manipulate[x,
 {{x, Round[.35, .05], "My Variable"}, Range[.2, .5, .05]},
 ControlType -> SetterBar]

Manipulate[x,
 {{x, .2 + 3*.05, "My Variable"}, Range[.2, .5, .05]},
 ControlType -> SetterBar]

Hello everyone,

I have a default value for a variable, x, in a Manipulate.  It uses a setter bar.

	{x, .35, "My Variable"}, Range[.2, .5, .05], ControlType -> SetterBar}

But unlike a slider whose thumb position moves to the default value when the Manipulate is first opened, the default value on the setter bar is not highlighted.  How can I get it to highlight so that users know where they are starting?

Regards,

Gregory
