When you attempt to open or save a file from various applications that use Windows File Open or Save As dialog, the dialog boxes may appear blank or with grey background, without the folder view or navigation pane. Here is how it might look like.
This happens if the Open or Save As dialog placement or MRU settings are corrupt, and here is how to fix the problem.
If following instructions in Step 1 doesn’t help, move on to next step.
- Clear Open / Save As Dialog Settings
- Reset Folder Views
- Run the System File Checker

Start Regedit.exe and go to the following branch:
