Well, there were some remaining “gotchas” in 4.0.1 that I’ve ironed out in 4.0.2. Most important were the troubles that Default Folder X was having with Open and Save sheets in Carbon applications when the app’s windows contained a toolbar. These problems are now fixed, as are a couple of smaller issues.
You can grab a copy of version 4.0.2 and/or read the change log here:
As always, thanks to everyone who reported the problems they found and helped test the fixes!
