[daip] FITLD problem

Wed Mar 16 04:55:12 EDT 2016

hi,

I started noticing some more funny behaviour in AIPS, and decided to nuke the existing install and start again. A complete re-install appears to have fixed the problem. I have no idea what was wrong before, but suspect some subtle corruption due to a file system glitch.

cheers,
Cormac
