It is possible to run multiple blockchains simultaneously within a single window - blockchain execution does not terminate when the associated browser window is closed.
Simplest example:
- Run a blockchain
- Close the browser window (which would be expected to terminate the operation).
- Reopen a new browser window
- Run another blockchain
The blockchain initiated in 1. continues to run and update the within the new window 3, alongside the independent run 4.
Similar issues exists with multiple windows open in parallel.
Suggested fix:
Terminate the blockchain execution when windows are closed, or prevent more than one blockchain being executed (by e.g. locking the start button). Perhaps raise errors or reboot when unexpected background processes are found.
