“The chart could not start.” or “The window is not responding.” in Senzoukria

What you see

In the footprint workspace, a pane stays on “Loading chart…” and after 15 seconds switches to “The chart could not start.” with a “Retry this chart” button. When you detach a chart, the workspace may report “Could not open: The window is not responding.” In a detached window whose page no longer exists, the text is “This page was closed or moved. You can close this window.”

Why it happens

Each chart pane runs in its own frame. The workspace checks every 100 ms whether the chart has mounted, and raises the alert after 15 seconds instead of leaving a white rectangle. It keeps watching afterwards, so a chart that finally mounts is revealed automatically. A detached window is created by the system; if its creation is not confirmed within 15 seconds, the attempt is abandoned with the timeout message. Heavy machines, a first start after an update, or several charts opening at once make these delays longer.

How to fix it

• Click “Retry this chart”; it reloads only that pane.
• Close charts you do not need and retry, especially if many panes open at once.
• For a detached window, try again from the chart’s Detach control; if it keeps failing, bring the chart back to the grid and reopen it.
• If the problem follows a performance issue, switch Settings → Performance to the Performance mode, which lowers the rendering load.
• Restart the app if every pane fails the same way.

What it is not

• Not a data problem: the frame did not start, so no data was requested yet.
• Not a sign-in problem, which has its own message in detached windows.

When to contact support

If the steps above do not change anything, send the case from Menu → Report a problem, or ask on the Senzoukria Discord. Say how many panes and windows were open, and copy any error shown by the “This screen stopped” card if it appeared.
