Hi David Golber,
Welcome to the Microsoft Q&A forum.
As mentioned by Q&A Assist, Office 2003 is not supported on Windows 11, for your reference: Support has ended for Office 2003. Word 2003 can still start and edit documents on Windows 11; however, some features (such as Save As and Insert Picture) rely on older file‑browser components. On newer Windows 11 builds, these dialogs may not load correctly, which can cause Word to stop responding when they are opened.
Here are some possible checking steps that you can try in this situation:
1, Turn off OneDrive Desktop sync
- Click the OneDrive cloud icon in the system tray
- Go to Settings > Sync and backup > Manage backup
- Turn Desktop OFF (Documents can remain ON)
- Close and reopen Word 2003
2, Start Word without add‑ins
- Press Win + R, type
winword /a and press Enter
3, Use Compatibility settings
- Right‑click
WINWORD.EXE > Properties > Compatibility
- Try Windows 7 or Windows XP (SP3)
- Check Run as administrator
4, Save to a local folder as temporary workaround
- Avoid OneDrive‑synced locations when using Save As
- Save directly to a local folder (e.g., C:\Docs)
For consistent access to all features, consider running Word 2003 in an older Windows environment (for example, a Windows 10 virtual machine), where these dialogs are known to function normally.
