"The mask is just 0 and 1’s"
you must use null and non null

I am not sure what you mean by “query” the map- under 6.4.3, when I open my
map with the mask file in my mapset, the map raster appears with the
sections I want visible, the sections I don’t want are not visible and
excluded from calculations. This is I think the expected behavior?
Under the beta 2 in both Windows and Linux (Ubuntu Trusty) I have tried
changing the color table on the underlying map raster but get the same
result- opening the raster with the mask present in the mapset blanks out
everything, removing the mask displays the entire raster. The color table
I’m using is greyscale. The mask is just 0 and 1’s, but I tried changing
the color table there, no difference. If I delete the mask file, the entire
underlying raster is displayed.
I verified the mask does contain both 0’s and 1’s, and like I said, it does
work fine under 6.4.
So I am stumped.

Did you actually query the map(s)?

The raster mask management is pretty much the same for years.
Perhaps it is just related to the color table you use?
