Script Debugger 4.5.3 from Late Night Software is a maintenance update to the AppleScript authoring environment. Changes include the pasting of object specifiers as a series of nested tell blocks instead of one object reference, an improved Balance command, automatic closing of AppleScript blocks, and the capability to continue when Script Debugger detects duplicate symbols coming from your libraries. Also several issues have been fixed including a hanging bug that occurred when viewing the InDesign dictionary, a bug that blocked auto-close and balance when unbalanced characters appeared in a style comment, and a bug that caused references to 'path' outside of a tell block to create incorrect 4-character codes.
