Extract by Mask doesn't obey mask extent

When attempting to extract part of a raster using a separate feature class as the mask the output is not reliably restricted to the mask area. Sometimes the output is confined to a similar shape of the mask, sometimes not at all (i.e. not changing from input raster whatsoever), and sometimes creates an empty raster (but still states it has been succesful). The randomness of output is what's very strange.

I am using ArcMap 10 and both the input raster and mask are in the same coordinate system.

I am also experiencing similar problems with Raster Creation whereby the tool seems not to obey the output extent.

Any ideas as to why this might be happening? Any work-around solutions also appreciated.

Cheers,
James
