Using Indesign 17.2 on x64 PC. Brand-new machine with fresh install.

To reproduce the issue open the story editor then close it.

Expected result: The story editor closes and I can resume working in the main document window immediately.

Actual result: When I close the story editor, the window disappears but all the tools on the toolbar, except the text tool, remain greyed out and I can't do anything in the main document for around 30 seconds.
