After many years, multiple versions of Premiere Pro, and multiple versions of Windows/Apple opperating systems, multi-screen workspaces are still not loading properly.
Specific Details:
This issue only occurs when creating a new project. If I create a new project, fix the workspace, then click "Save Changes to This Workspace", close Premiere, then reopen that project, the workspace loads correctly.
The main culprit is the "Project" panel - the panel that includes Bins, Meta Data, Sequences, etc. And the incorrect loading place is different every time.
