Default Folder X 4.4.7 fixes several bugs that resulted in crashes or incorrect behavior. At it’s worst, one bug could actually cause Save As dialogs to crash in Keynote, and resulted in Bias Peak not responding to mouse clicks. Because of the nature of this problem (it could impact just about any application), we strongly recommend that everyone using Default Folder X 4 upgrade to version 4.4.7.
So go to the Default Folder X Release Page and download a copy now. And as always, if you run into any trouble or have comments or suggestions, just let us know!
