Bug with showdensity, hidepoints and windowhide ?

["marsupiofr" <marsupio@xxxxxxxxxxx>]

Hi folks,

when I call in a LUA script runpost("Postprocessor.lua","-windowhide) 
and when I perform in the Postprocessor.lua the following 
instructions :

hidepoints()
showdensityplot(0,0,0.05,0,"mag")

then bitmap picture saving, the points are not hidden and the density 
map is not drawn. Do I do something wrong or is there a problem ? No 
problem when the -windowhide is not activated.

Thanks for your comments.
