BuddyPress.org

This problem has been bugging me for a long time. When deleting an activity update by clicking the “delete” button below it, sometimes I see the “Are you sure” dialog box for me to confirm the deleting, but at other times the activity update is deleted without the “Are you sure” dialog box.

I have tested this on testbp.org and my own test site. Here is what I found:
1) Right after posting an activity update, no “Are you sure” dialog box shows up if I click the “delete” button. The activity update is just deleted.
2) After posting an activity update, if I refresh the page then click the “delete” button, the “Are you sure” dialog box shows up for me to confirm the deletion.
3) If I refresh the page, select any of the filter ( everything, updates, new groups, group memberships, etc), then all my activity updates can be just deleted without seeing the “Are you sure” dialog box.

It should be required for users to confirm the deletion all the time. Otherwise they would be confused and frustrated if deleting something by accidence. What can I do to have the “Are you sure” dialog box all the time?

Thanks.
