This is a know bug of the version 3.3 that causes the freeze of the current open database when switching from Card view to Table view.


To unlock the database, as temporary workaround, please use the "View" menu to switch back to the Card view.




We released a new version that fix this bug, you can download it from our Download page.


NOTE: users of Mac App Store don't need to download the new version from our site, it will be available directly in Mac App Store.
