Summary0019904: Form Designer weirdness -- select hidden control, depndent on creation order
DescriptionOn a new form, in the designer:

- Put a button
- Put a label

Move either of them, so they partly overlap (the label will be hidden)

Click (left mouse) the area of the overlap => the label is selected (unexpected?)

Put an other label, and button (but this time the label first) on the form, and repeat. Now the overlap selects the button.

It seems that the click selects the last created component, if the overlap. (Not sure if this is true for all combinations of controls, only tested this one)
TagsNo tags attached.

Same as 0007886

Since OnChange and OnPageChanged properties point to the same internal variable, and the event is triggered by both names.

What has OnChange to do with this issue?
