I just updated my all-time favorite Twitter client Twitterrific to the latest release on the App store, lo and behold all of the text is inverted. I really hope this can be fixed easily and they didn't punk everyone who's still using the desktop (OSX) client.

Update: I got a response from The Iconfactory, who make Twitterrific, they said that this is caused by a bug in 10.7 that was fixed in 10.9 - they'd updated the program in v4.5.1 to work with 10.9 but that meant that it then didn't work correctly with 10.7. So the solution is: don't update to Twitterrific v4.5.1 if you haven't upgraded to 10.9 yet.
