Ever since upgrading to Yosemite, I've had nothing but problems using Font Book.
- Creating and switching between collections causes huge slowdowns.
- Viewing a Smart Collection causes the app to hang 100% of the time, and must be force quit.
- Viewing different fonts and styles takes much longer to load than before.
- Having added a font to my library today, I can no longer launch it without it hanging on start. Now it's completely unusable.
Anyone else having huge issues with it?
