If you’ve installed last week’s update for TaskTask, you may encounter an issue where TaskTask repeatedly crashes. Unfortunately there was a test case that I missed while working on that version that does cause TaskTask to crash in a rather common scenario. I’ve just submitted a fix for the issue to Apple and have requested that they fast-track approval of the update due to the crashing issue. If you haven’t updated already, I recommend waiting until the 3.2.492 update is released to update.
Sorry for the troubles, I’ve updated my set of test cases to make sure I have good coverage on this particular type of issue in the future.
Edit: There also appears to be an issue with iOS 5 devices not being able to connect to some servers. An error message indicating a problem with SSL will be displayed, and you will be unable to connect. I’ve tracked down the root cause of the issue and have also provided a fix in the upcoming 3.2.492 update.
