Chart Activate event not triggered when workbook opened?

[kk_oop]

Hi. I wrote some code to run for a particular chart's Activate event.
This works fine, but for some reason, if that is my current chart when
I open the workbook, the Activate event does not get triggered. This
seems strange since, in this case, the chart is being displayed.

Is this a bug? Or at this point, is the chart not truly activated,
i.e., is the Activate event really not supposed to be triggered in this
case? Also, what chart event does get triggered in this case?

Thanks for any info,

Ken
