Thank you for suggestion, but still it is showing double panel, with vertical column, in between, even though "Studio mode is switched off, from control panel on the right." Whatelse could I do to remove it and restore single panel?

1. Main menu File>Show Settings Folder (file explorer window will appear).
2. Close the OBS program.
3. In the still opened file explorer window navigate and open the "global.ini" file with notepad++ editor (or similar program that understands LF end of line writing).
4. Find the string: PreviewProgramMode=true and change it to PreviewProgramMode=false (the string is in the [BasicWindow] section of the file).
5. Save the changes.
6. Try to run OBS again.

Any changes?
