Version 2.7.040 was just uploaded. This is a maintenance release that solves a row of issues in the previous release without adding any big features:

• Improved undo history tracking and item validation, solving the "invalid item" exceptions that often occurred in connection with undoing.
• Fixed issues with tablet data arrays, where setting one type of tablet data would erase all the others.
• Display spin edit controls correctly on PC.
• Improved working with layers, fixed layer.clone() and hierarchy traversal using layer.previousSibling / layer.nextSibling.
• Palette windows now remember their last position.
• Prompt and alert dialogs now appear centred on the screen.
• Scriptographer window is displayed by default when first launched.
• The Hide / Show Scriptographer menu entry is not confused anymore on the first launch.
• Added item.index, returning the index within the parent's list of children.
