What

Inside common Windows file dialogs, Claude can now only type into the File name box. The address bar and search band refuse typing, and right-click, Alt-modified clicks and drag-and-drop inside the dialog are blocked outright.

Details
  • Multi-key chords must be sent one key at a time inside a file dialog; tab and newline characters in typed text are refused.
  • Refusals carry the reason code file_dialog_restricted, new in this build.
  • The checks only run when the platform is win32 and the host reports both the focused control and the control under the pointer; otherwise the dialog is treated as an ordinary window.
Evidence

file_dialog_restricted

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
