Hi, I've tried searching for this but there seems to be alot of misunderstanding as to what is being asked, so please forgive the length of this post. Running Windows 7, Thunderbird 115.15.0 (64-bit). On opening Thunderbird or when a reminder point for a calendar or event is due a Reminders Window Pops Up showing all reminders/events. I can dismiss individulally or All or snooze indivulally or All. There is also an option [X] to close the window. Q, As to my actual question, if that window is closed, for what ever reason, I can not find away of re-opening the window, any help on how to do this? Please note I am not referring to the "Today Pain" which I can show or hide as needed. As an example I may have an appointment due on the 12th of the month, but need to prepare for it so I set a reminder for 3 days before, ie 9th. So on the 9th a reminder for the appointment appears allowing me to dismiss or snooze. I would commonly start to prepare and as such leave the reminder as is, not clicking dismiss or snooze but closing the window. Later on in the day I wish to open the window so I can clear the reminder. That's the window I wish to open and do not know how. Snoozing will not help as I may not be able to predict how long it takes me to prepare and therefore can snoze for too long or too short. I've included a screen shot of the actual window in question with a dummy reminder. Hope this was too long and thanks for any help offered.
