Comment 2 for bug 16417

I've been trying to think of a way to describe what seems to be a similar bug.
When using Synaptic (as an example), I notice that if my mouse pointer is placed
over a dialogue button the system fails to recognize that it can be selected.
Thus, I must move my mouse pointer away from the button and hover back over it
to get Ubuntu to recognize it again. This seems most common when I want to
refresh a window to check for changes/updates. I would think that the button
would become active again after the task is initially completed. Why do I need
to push a button twice? I'll be darned if I can remember, but this issue did
annoy me.
