An application Open or Save dialog is not the same interface as a normal File Explorer window. Open-Shell documentation does not promise to add an Up button to all application dialogs. Troubleshooting a frozen dialog is also different from requesting a new toolbar feature.
What to do
- Identify whether the problem occurs in Explorer or within an application file picker. Record the application name and the exact Open or Save action.
- Test a local folder path to distinguish a slow network destination from a dialog-integration problem. Keep unsaved work protected during testing.
- Compare the installed Open-Shell version with release notes. Version 4.4.198 includes a correction related to Open/Save dialogs getting stuck after a Windows 11 update.
- Reproduce the issue with a minimal configuration and report the Windows build and program version. Do not assume a preview or an unrelated toolbar option is required.
Check the result
Open and close the same application dialog several times using a local folder. Confirm that selecting or saving a file completes, not merely that the window appears.
Limits & precautions
The presence of a documented fix does not prove that every frozen file dialog has the same cause. Application extensions, unavailable folders, and OS changes may need separate investigation.
Questions & answers
Can Classic Explorer add an Up button everywhere?
The project FAQ explicitly rejects that general promise for application file dialogs.
Is a frozen Save dialog only a skin issue?
No. Check the release notes and the exact application and Windows build.
