Thanks, AbteriX - the version number updated, to 1.6.9. now. The link hasn't changed.
Anyone who downloaded this version before 28 Dec 2006, please update with today's bugfix. When I said (elsewhere) that KeyNote was unmaintainable, I told the truth! There are, for example, several paths in the code that can lead to creating a new tree node, and as a result, the advertised new feature didn't always work: new nodes didn't always get their creation date assigned.
Learning is a good thing, but it makes you cringe when you look at code written six years ago...
(For the coders here - I can't set creation date in the constructor, because all your "old" nodes would appear to have been created the day you opened an old file with the new version of KeyNote. Nodes have no creation date if the knt file doesn't carry this information, so only newly created nodes acquire the date.)
Anyway, this new release fixes that, and I'm hurrying back to my current project, which will hopefully be less jinxed
