On p72 (beta2) we hide the extension of the cache files. “Here’s a screenshot”:http://skitch.com/drnic/99fk/why-is-extension-being-shown of the cache files in Finder which show the extension being displayed when they should be hidden. The extension also shows up in Spotlight when it should be hidden there (where I first noticed the problem).
It also shows the Info panel which shows the “Hide extension” checkbox ticked.
The screenshot also shows the MacRuby code used to change the file attribute.
Any one know what might be happening?
