Unresponsive Modal Windows in SSMS Database Diagram Floating Windows

Description:

I am encountering a persistent issue in SQL Server Management Studio (SSMS) where modal windows, such as the "Save" dialog, become unresponsive when using floating windows within database diagrams. This occurs when I switch focus from the floating window to the main SSMS window.

Steps to Reproduce:

1. Open SSMS and create a new database diagram.
2. Create a floating window within the diagram.
3. Trigger a modal window (e.g., by attempting to save the diagram).
4. Shift focus to the main SSMS window.

Expected Behavior:

The modal window should remain responsive and allow me to interact with it.

Actual Behavior:

The modal window becomes unresponsive, preventing me from proceeding.

Workarounds Attempted:

I have tried the following workarounds without success:

• Minimizing the main SSMS window
• Moving the floating window
• Switching to a different window and back
• Atempting to use full-screen mode

Additional Information:

• SSMS Version: SQL Server Management Studio 20.2.30.0
• Operating System: Windows 11 but I had the same problem with Win10

I request that Microsoft investigate and address this issue to improve the usability of SSMS for database diagram design.
