Default Folder X 4.6.11 is available now, bringing you a couple of important fixes when running on Yosemite. The first is a bug fix for a crash that occurs under some circumstances in Carbon applications such as Adobe Photoshop and Microsoft Word. The second is a more minor problem with BusyCal and BusyContacts, where Default Folder X would prevent one of the initial setup dialogs from defaulting to the proper folder.
You can grab the new version from http://www.stclairsoft.com/DefaultFolderX/index.html. This update is free for anyone who’s purchased a license for Default Folder X version 4.
