SupportedModes

In CS5, when I set

-------------------------------------------------------------------------

SupportedModes

{

     noBitmap, noGrayScale,

     noIndexedColor, doesSupportRGBColor,

     noCMYKColor, noHSLColor,

     noHSBColor, noMultichannel,

     noDuotone, noLABColor

},

EnableInfo { "in(PSHOP_ImageMode, RGBMode, RGB48Mode) &&"

                    "(PSHOP_ImageDepth == 8 || PSHOP_ImageDepth == 16 || PSHOP_ImageDepth == 32)" },

-------------------------------------------------------------------------

to work only with RGB, my plug-in is still active (black) in Photoshop's menu in "Lab Color" mode. What I have missed?

Thank you,

Sergey
