umask question

[hanfamily earthlink net]

Hi,
I have a question on umask with 6.2 I could use umask to set
permissions and all the files created by the user had the
right permissions. I find with 7.2 that files created by
many programs create files with only user having rw permission
instead of the group and user having rw permissions. Does anyone
no how to make the permissions uniform for everything.
              Thanks
               Linda
