Here's a few things that have been fixed/tweaked since the last beta:
- No longer crashes randomly when updating.
- Send Tweet window auto-closes when your Tweet is sent.
- The height of each Tweet is now ALWAYS large enough to fit the text in.
- The local time set on your device is now taken into account when displaying Tweet times.
- The direct message timeline now works.
- The drawing of each tweet is now done using double-buffering to minimize flicker.

Installation:
Copy the CAB file to your Windows Mobile device and run it, the CAB installer will install Quakk and create a shortcut in your Programs menu.

You might need to download and install the .NET Compact Framework 2 if you're running Windows Mobile 5.0.
