When you browse your mouse over a WebDataMenu, and it pops up a menu, you must be very careful where you position the mouse or the popup will automatically go away.
If your mouse leaves the WebDataMenu (even for a fraction of a second) the popup menu will hide itself.
This happens frequently when you take a shortcut from the WebDataMenu to the popup. In other words, if your mouse takes a direct line from the WebDataMenu to the popup that isn't directly over any menu parts then the popup will go away.
I have illustrated a very common occurrance that causes the popup to hide itself. See the attachments.
Is there a solution?
