From time to time, I go through periods of time when I cannot delete my email ... it says on top "Thunderbird program not responding" & then goes blank ... either I can leave T-bird or wait for program to respond which takes a couple of minutes ...

I need help to know why it is doing this.

Thank you!

The most likely cause is an anti virus program misbehaving. That includes windows defender which is not always well behaved.
