where's it leaving the blank?  dviwindo, dviwindo-printed output, or
dvipsone output?

there's obviously something wrong with your configuration, but without
someone with the appropriate experience seeing the relevant .ini files,
it's hard to say what.  i presume the mathtime fonts do appear when you
look for installed fonts using the windows font browser?

i'm afraid i'm not the one even to say which ini files you should
forward, but someone will surely come along.
