  We present subarcsecond observations at 2.7 and 1.4 mm of a sample of massive
young stellar objects made with the BIMA millimetre array. For most sources the
continuum emission on the smallest scales at 2.7 mm is dominated by free-free
emission from the stellar wind or jet. Strong emission at 1.4 mm shows the
presence of significant dust associated with Cep A and GL 490 but our
resolution is not sufficient to resolve any structure. The 2.7-mm emission from
GL 490 is resolved but it is not clear whether we are seeing a single
circumstellar disk or a secondary companion, although near-infrared data
support the disk hypothesis. Estimates of the dust mass yield values of ~1--4
Msun within radii of 150 to 1000 AU.
