Alert Notification Pop Up History log Radarbox 6.01.001

[GreekSpy2001]

Can anyone tell me where the alert notifications histroy log are held.  I notice after a while they take a log time to appear and  halting the RDB sw for a few seconds.  Can become very irritating if a lot of alerts hit at the same time waiting for all of them to come thru before the screen updates.  I can correct this by restarting the sw which flushes the alert message history.  But can I do this without restarting the program?

Tks
