Yet Another IDL 8.2.3 Anomoly with Window Refresh [message #84914]

Folks,

I have some function graphics code that produces a box axes on a map.
Because this involves a lot of "after the fact" manipulation, I usually
turn window refreshing off so the user doesn't have to see all the
machinations. But, the window refresh has seemingly gone South in IDL
8.2.3.

Here is an example program. It works perfectly until you set the REFRESH
keyword. Then, you just see a big cross in the graphics window. :-(

;***********************************************
PRO Window_Refresh_Bug, Refresh=refresh
win = Window()
IF Keyword_Set(refresh) THEN win.refresh, /Disable
mp = Map('Equirectangular', CENTER_LONGITUDE=180, $
BOX_AXES=1, GRID_LATITUDE = 30, GRID_LONGITUDE = 45, $
LABEL_POSITION=0, LIMIT=[-89.99, 0, 89.99, 360], CURRENT=win)
mp['Latitudes'].label_angle=90
mp['Longitudes'].label_angle=0
grid = MapGrid( $
LONGITUDE_MIN=0, LONGITUDE_MAX=360, $
LATITUDE_MIN=-90, LATITUDE_MAX=90, $
GRID_LONGITUDE=45, GRID_LATITUDE=30, $
LABEL_POSITION=1, CURRENT=win)
FOREACH g,grid.latitudes DO g.label_angle=270
FOREACH g,grid.longitudes DO g.label_angle=0
c = MapContinents(Color=!Color.red)
IF Keyword_Set(refresh) THEN win.refresh
END
;***********************************************

Cheers,

David
