Event On Mouse Leave question.

I have a UI widget in the top right corner of the screen that overrides Event On Mouse Enter. When this event fires a popup window appears on the top left of the screen.

When the popup appears it causes the Event On Mouse Leave event of the top right corner widget to fire. I don’t understand why this is happening because I did not move the mouse off the widget. Also the popup does not overlap.

Any thoughts?

Well… I noticed this problem goes away if I create a main widget and add each of the above widgets as children. The problem is that my widgets are no longer in the position I want them in.
