cgWindRose has error producing legend? [message #89472]

Hi - I am using cgWindRose for a little exploratory work. My input data are straightforward, hourly observations from a NDBC buoy. I just remove the missing data and call cgWindRose:
;
good = WHERE(wd NE 99.00, ngood) ; Missing wind data have value 99.00
cgWindRose, wspd[good], wd[good], TITLE = buoyName+STRING(year, FORMAT='(I5)')
;
I do get a wind rose, but two things are strange. First, it looks like the rose isn't sized correctly for the window - the "East" label is cut off - and second, I get a legend heading "Wind Speed (m/s") but no legend with the error message:

Traceback Report from CGLEGENDITEM::INIT:

% CGLEGENDITEM::INIT: Number of COLORS elements not equal to the number of legend items.
% Execution halted at: CGLEGENDITEM::INIT 234 /Users/blesht/IDLStuff/coyote/cglegenditem__define.pro
% CGLEGEND 200 /Users/blesht/IDLStuff/coyote/cglegend.pro
% CGWINDROSE 363 /Users/blesht/IDLStuff/coyote/cgwindrose.pro
% LSUP_WIND_STRESS 35 /Users/blesht/IDLWorkspace82/Default/lsup_wind_stress.pro
% $MAIN$

I'm running IDL8.2.3 on MacOSX10.8.5 and my Coyote library is current through revision 1494. I don't have any other graphics calls (e.g. color tables, etc.) before the call to cgWindRose.

I haven't seen any other posts reporting this (or any other issues with cgWindRose), so I'm probably doing something wrong, but I haven't figured out what it could be. Any help much appreciated.

Thanks, Barry
