Combine Tool Produces Output Raster with No Values

I'm trying to combine four rasters, each with the same number of bands (1), resolution (8 bit), and spatial reference (NAD_1983_StatePlane_Washington_South_FIPS_4602_Feet). I used the combine tool a couple weeks ago for this process and it worked fine.

Since then I've been upgraded to 10 and have run the tool with the same inputs. The output raster is added to my table of contents with a range of values displayed but there is nothing visible in the data view and the resulting table has no values.

The combine tool works fine with just two of the inputs (any two randomly selected), but it doesn't seem to like more than that.

I've had the same issue with other spatial analyst tools combining multiple rasters, such as weighted overlay and weighted sum, where the tool runs successfully but the resulting raster has no values.

Has anyone else encountered this issue?
