MultiCharts: Trading Software for Automated Trading and Backtesting

Any time I try to change from online to offline or vice versa (in Preferences - Data Server Mode), I get the attached error.

The only solution is to close all workspaces, change the online/offline mode and reopen workpaces (which can take a lot of time until ready because each workspace has a lot of charts linked to Interactive Brokers and they start to backfill for a while).

Any way to do this change online/offline without closing the workspaces ?

NO. You have to close all workspaces first.
I believe this is done to avoid accidental switching which can cause unintended trading activities.
