I don't know that this is actually the problem; you may have to dig in a little further.

Actually, we get the original mouse-down but when trying to find where the mouse is in the view using [contentView hitTest: mouseLoc] it was always returning the AVHTMLView containing our view, even if the mouseLoc was in our view and our view was ordered before it and enabled and isOpaque returned trye.

It turns out that [NSView opaqueAncestor] has code in it specifically for WebHTMLViews, and even though our view returned isOpaque the event went to the WebHTMLView ancestor behind your view because of this code.

Assuming that you will accept that the view you're controlling will not work as part of a transparent layer (i.e. no warranty is expressed or implied but it worked for me and I'm willing to live under those restrictions), you can add this to your own NSView subclass:

- (NSView *)opaqueAncestor {
    if ([self isOpaque]) {
        return self;
    } else {
        return [super opaqueAncestor];
    }
}

...and try it out. Note that our method flow is different (we don't specifically send events), but this smells like the same problem.

I should note that this is part of an as-yet unreleased product, and while our testing has shown no problems, we can't know for sure what will happen when it goes out to the wider world (can you tell I'm trying to cover my posterior as much as possible here?)

Hope this helps,
Rudi

Yes, I have HTML in the view.
It's pretty simple, no frames, just a few divs and some javascript to
allow dragging.
Can you describe a bit more about what special mouse-tracking loops
you had to do?
Thanks for your response!

Do you have HTML in the view? I found that WebHTMLView does some strange things with mouse-events and sometimes swallows them; I believe this is to handle HTML layering. I have a plug-in and I had to do special things during mouse-tracking loops whenever my plug-in was inside a frame or embedded, that I didn't have to do with my plug- in was the entire document.
Hope this helps,
