I am experiencing a series of problems with the Events panel.

1. Customer's like to have the Event panel opening with the same content from multiple WS. The settings I have in Events Timerange are: Open, Historical Data, Central Settings. And I get 90 min of data before the panel is opened. Obviously if the panel is open from another WS 30 min later, the data I get will be different. Customer's expected a behavior similar to the Alert panel , each instance opened from any client is exactly the same.
Is there any way we can at least approximate that behavior (I know events are different , but we are having hard time to "sell" it to our customers).

2) after a long use of the Event panel, the automatic scrolling doesn't work anymore. Thus when a new event is logged, you don't see it unless you manually scroll to the end of the list. I don't know what is causing this behavior. Any fix ?

1) If you open the Event Screen with historical data ("Open + historical data") for a given time period (e.g. 90 minutes) you will get result A.
When you do the same a few minutes later you will never get the same result A as new data was written in the meantime and the time period is different.
When opening the Alert Screen in the same configuration "Open + historical data" at different time you will get the same behaviour. There is no difference.

Only for the Alert Screen in mode "Current" you will have the same result if the screen is opened at different times.
Getting the same behaviour in the Event Screen is not possible.

2) What does "long use" mean in detail?
Can you reproduce the problem in a test system?

Thanks.
N.2 works the following. If for example you select Max Num of lines 10, after 10 lines the events are re-written on the same 10 lines. So if you have a number larger than the windows size, say 200, after that number the panel doesn't scroll anymore because events are re-written on the same lines, but the will be not visible, being at the bottom of the screen. The only way is to manually scroll to the end.

We have a large number of events I use Max Num 100,000 and it seems to be ok, but I am not sure that after that number the events will not scroll down. In Central settings I have Maximun no. of lines (close) 10,000 is that number related to the Max Num of lines in the Event panel?

The configuration in "Central Settings" is related to the maximum number of lines for a historical data request.
I tested it with the Event Screen and 200 lines. New events have been displayed at the end of the table and the last line was always visible.

If I have read it correctly you are displaying 100.000 lines in the Event Screen in "Open" mode.
Why are you using such a high number of lines?

From our point of view reading information in a table with 100.000 lines is not easy and therefore it is better to use a smaller amount of data.
