I just updated Checklist Tree to version 1.2.  Here’s the changes:

• Requirements change. Now requires .NET Compact Framework 3.5
• Hardkeys do things. Left/right expands/collapses node. Up/Down scrolls through. Center button press selects/deselects.
• Last used file is stored in the registry and will open when the app starts up.
• About dialog with support links added.
• Versioning scheme changed to Major.Minor from DATE
• Context menu now has an option to copy the node contents to the clipboard
• HTML Changelog (this file)
• New icon

Go check it out in the software section.  Remember to uninstall any previous versions of the software before you install the new cab.
