At the first of the year, I decided that I needed HeaderTools badly enough that I would backlevel Tbird to the last release in which it worked. Last week, I vowed that it would be the first thing I did this week. I had just finished backing up my system and downloading the installer for TB60.9 when I little bird :-) whispered in my ear, "Check for a new version of HeaderTools one last time before you do anything drastic."
Bless You, Dillinger!
This utility belongs in the small cadre of such stupendously useful "free" software that I am willing to support it financially. How may I do that?
And WHY isn't it an integral part of Tbird?
