I tried reporting bugs via the support web form, but we never receive a response, so trying here as I don't know if the report made it to the team. We have a "Team4" license if someone from NuSphere can contact me if needed via the email address of my forum account.

Now... on to the bug...

With v21020 installed over v21018 (since v21019) did not work for us due to high-DPI bug....

Problem: Center editor window does not return to its original display height when closing the optional windows that appear below it.

To Reproduce: Open PHPEd full screen, and search for some text across all files in the project.
- The "Search Results" window will open below the 3 main sections as it should
- When you close the search results with the "X" to its top right corner, only the Workspace on the left, and the Code Navigator to the right will return to the height of the screen
- The middle Editor/Preview window will not extend back to where it should be

Solution: Reverted back to v21018 again in order to have proper working program

Apologies for the delay.

Issues with window docking can be challenging to reproduce, especially if you’ve customized the UI. Even if the IDE itself hasn’t been customized, using a custom Windows UI "improvement" software can sometimes trigger problems with the Windows stack. Specifically, Windows tracks stack depths when sending WM_WINDOWPOSCHANGING/CHANGED events. If the stack depth exceeds a certain threshold, Windows stops sending these events, which can leave some nested windows misaligned. I believe this might be what you're experiencing.

Here are my suggestions:
a) Test on a clean Windows machine running the same OS version, but without any customizations.
b) Try resetting the IDE layout View -> Restore Default Layout then restart the applicatoin.
c) Switch to the default color scheme to rule out any theme-related issues.

Let me know if this resolves the problem or if further assistance is needed
