When using the app with subagents, after opening them to toggle the tabs and view progress, the grabber mouse icon is stuck. Nothing recovers to be able to use anything in the app. Only can minimize or maximize the app and can close. Have to fully exit and lose work progress entirely.

What steps can reproduce the bug?

Create subagents.
Open them in the sidebar.
Click between them to read their outputs.
Experience rage from seeing this and not being able to complete a session!

What is the expected behavior?

That the tabs work and don't get stuck.

Additional information

It's hugely frustrating. It's disruptive of workflow. It's unexpected.
