Event case missing mouse events on active-x component

[WPS]

I am using a Treeview and capturing selections in the tree using mouse events (event structure). I have a problem where approx 3 out of 15 mouse events are not actioned by the event structure - has anyone else had this problem or is there any suggestions?
Thanks.

Could you post a copy of your code that demonstates this?

I have experimented with this control and its events.

We may be able to help if we have soething to look at.
