In the past 48 hours, several things are failing:
1) While writing a post, I can no longer access the font palette to select my font or change the font size. (I'm working on a Mac, and I used to be able to access this with a right-click in the body of the post)
2) WordPress has repeatedly frozen when I've attempted to save a draft, and
3) has repeatedly (but not invariably) failed to let me see a preview when I've clicked on preview
I generally use safari as my browser, but have tried chrome and firefox and the same problems remain, so it seems to be a WordPress issue.
