Bug ID: 52711
           Summary: Cakewalk Pro Audio 9.0 no longer works in wine 7.4
           Product: Wine
           Version: 7.4
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

The application just shows a message box saying "failed to create empty
document" after starting up. Creating a new project and opening an existing
file won't work either, rendering the application useless.

An installation of the application will be provided if requested (runs well
with fresh wine prefix before 7.4).

I did a bisect and traced the first bad commit to

passing window classes internally.)
