Version 5.7.4 of Default Folder X is available, addressing several issues that could impact its reliability in Open and Save dialogs. These ranged from the mundane – a timing bug in the code that switches to new folders in file dialogs – to the “I wouldn’t have guessed that” – where Safari’s SandboxBroker helper app was tricking Default Folder X into thinking there were actually two Save sheets displayed at once.
All of these issues happened infrequently enough that they only generated a few tech support requests (my apologies to those unlucky folks), but chasing them down and getting them fixed will ensure that they don’t disrupt anyone else’s day.
The complete list of fixes and download links are on the Default Folder X release page. Or if you’re already running Default Folder X like you should be, just choose “Check for Update…” from its menu in your menu bar to see the change history and update to the new version.
