I just downloaded and installed it with no issues. I'll be working on a script tonight so will report if I find any.
Here are the minor improvements in the update:
Send to Script: Send content from your Index Cards (Summary Side) right to your script with a simple mouse click.
Text Highlighting: Highlight text using the new toolbar icon and its five bright colors.
Script Compare: Compare two drafts of the same script right down to individual words and punctuation.
Print to PDF: Now also accessible from the File menu.
