I first thought this was happening only when trying to paste a hyperlink to a Note or Clipping (the new features as of 4.0d) but it seems to be happening with any hyperlink (even to a web page).
- Open any resource.
- Copy location as URL.
- Open an existing Notes file or choose File > New > Notes
- Click Add Note
- Paste (Ctrl+V)
- Click on any other tab.
- Click back on the Notes tab and click at the end of the note you just added.
Result: Logos Crashes. Very repeatable.
Crash error is "InvalidOperationException: Cannot split 'Hyperlink' element at this position."
Indexer was still running when this happened (if that matters).
I've tried this with different variations (getting the hyperlink from different resources, web URL, Notes, Clippings; different orders of clicking on things after pasting into the note, etc; the crash reproduces in many different scenarios). Here are the log files from one such trial -- I think identical to the steps I outlined above: 8032.NotesHyperlinkCrash.zip
