What's Wrong?

When I right-click a file hyperlink in the Code section, the context menu opens correctly (Attach as context, Copy path, Copy relative path, Copy filename, Open in ›). But when I hover over or click the "Open in ›" item, the nested submenu does not expand. Instead, the entire context menu immediately disappears, leaving no menu on screen. I'm unable to reach any of the "Open in" targets.

Error Messages/Logs

None observed. (No error toast or console message appeared; the menu simply vanishes.)

Steps to Reproduce

Steps to Reproduce

Open the Claude Desktop app and go to the Code section/tab.
Locate a file hyperlink in the output (e.g. …development/PROJECT-REPORT.md).
Right-click the hyperlink — the context menu appears.
Move the cursor to the "Open in ›" item at the bottom of the menu (it highlights).
Observe: the submenu does not expand; instead the entire context menu closes and disappears.

Additional Information

This is a GUI bug in the Claude Desktop app's Code section, not a CLI/terminal issue. The other context-menu items (Copy path, Copy relative path, Copy filename, Attach as context) [confirm whether these work when clicked — worth verifying, as it tells you whether the bug is specific to the submenu trigger or a broader menu focus/dismissal issue]. Screenshots attached: (1) context menu open on the hyperlink, (2) cursor on "Open in ›" highlighted, (3) menu fully dismissed.
