Please describe the problem:
Placing the mouse over a disabled button, which then is made enabled as a result of another action or process completing prevents the button from being clicked until the mouse is moved off the button and back onto it.

Steps to reproduce:
1. Open "Computer" from the "Places" menu
2. Place the mouse over the "Refresh" button on the top toolbar
3. Press F5 on the keyboard to manually refresh the contents of the window (do not move the mouse at all)
4. Click on the Refresh button on the top toolbar (without moving the mouse)


Actual results:
Steps 1-3 work as expected. Step 4 does nothing - it does not refresh the contents of the window.
In order to work around this, the mouse has to be moved off the button and back over it again in order to be able to click on it again.

Expected results:
Clicking on the Refresh button in step 4 should refresh the contents of the window

Does this happen every time?
Yes. In all Gnome programs as far as I can tell.

Same behaviour is experienced in the "Update Manager", holding the mouse over the "Check" or "Install Updates" buttons while the software is "Staring Update Manager" (for example).
