Quotes in another workspace tab are not moving

You see: you switch to a workspace tab and its quotes are stale, or a tab you left shows prices that no longer move.

Why (by design): only the workspace on screen holds market-data lines. A background tab does not stream, so it does not use your line allowance. The lines move to the tab you switch to.

What to do: switch back to the tab. Quotes resume. The status bar’s Lines item shows how many lines are in use.
