Just did a fresh install of 2013 sp3.0 on a new computer.
Now my drawing tapped hole callouts display the leading hash tag (#10-24) rather than (10-24) as it did before.
I need it as it was
Well if anyone else wanders into this problem, I found the solution.
In the calloutformat.txt file the tapped hole lines were using <hw-threadsize><hw-threadseries>
My earlier version of the file was using <hw-threaddesc> only.
