Hi PJM,

I think I finally understand this post as it is different from the complaint that you linked to. Just to confirm, the vi that is non frontmost will not register an event waved over the frontmost vi that also covers part of the vi that is behind it. This does not seem at all a bug to me, even though frontmost does not mean that the front most vi takes priority, it however it does mean that the vi take priority of that specific space on the front panel and therefore the vi behind it should not register anything because its not looking at that part of the front panel. The non front most vi does register the mouse over event for the parts that are not overlapping and thats what it appears that was the problem you linked to was complaining about, with the vi registering the event regardless if it was foremost or not.

It almost appears that you are concerned about both sides of the spectrum here, with the vi registering the event both regardless of foremost and also saying that it does not register if non front most. Am I correct about this?

Andrew,

I am the person who posted on LAVA.

I think there is a misunderstanding in here. The fact that one VI is partially behind another one has nothing to do with the bug. The issue is as follow:

• On windows every VI (for the sake of this discussion let say non overlapping VI) who register for a mouse move event will receive the event when the user move the mouse over its front panel (which is expected).
• On Mac, only the front most VI will receive the mouse move event. If you happen to be moving the mouse above a non front most  VI, the event is not fired (which is not expected).

I hope this clarify the issue.

Hi PJM,

Thanks for clarifying the issue. I have gone ahead and tested it on one of our mac's and I can verify what you say. I will make a bug report for it. Thanks for bringing this to our attention.
