[Bug 32434] network-admin, clicking [OK] fails if pointer is above button before it is made active

[Paul Sladen]

Public bug reported:
https://launchpad.net/malone/bugs/32434

Affects: gnome-applets (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed

Description:
If the pointer is moved over an button that is currently disabled
("grayed out") and then that button is made active (by enternal event,
such as the completion of a DHCP request) then it is not possible to
"click" the button without moving off the icon and then back over it
again.

Very likely this is because something is hooking 'onmouseover' and this
when the button goes from disabled->enabled as the pointer is already
within the bounding box ('onmouseover' event occured earlier, whilst the
button was disabled).

Reproduce:

 1. System->Preferences->Networking
 2. Select an interface.
 3. Click [Deactive]
 4. Click [Active]
 5. Whilst the activity bar is appearing, move the mouse pointer to the OK button in the parent window, see:

 6. When the button becomes active, try to click it, this will not work.

This issue could be GTK-wide, or it could be the way that the just the
Networking Panel is enabling the button.
