Comment 8 for bug 12246

Same problem here, i386, hoary. However, it happens any time synaptic is 'busy'
with something else. It seems as though the buttons are disabled (not visibly)
while another operation is executing (such as the database loading), and are
afterwards only clickable when the mouse moves onto the button (i.e. not if the
mouse is already over it).

Additional steps to reproduce:
1. Launch Synaptic.
2. Move mouse over any (active) toolbar button, before initial database loading
completes.
3. Try to click the button once loading completes.
