Prevent Terminal subwindow from switching from "Experts" to "Mailbox"?

 

Hello,

I record my MT5 screen with special interest on the MetaTrader "Experts"-tab (for bug-detection and price analysis), so it's really annoying that any incoming e-mail from my broker automatically switches to the "Mailbox"-tab instead. Is there an option in the MT5 settings, in MQL5 or any other way to prevent those switches?

Many thanks in advance!
