Comment 6 for bug 84267

Well I am going to describe the problem more preciously.
If it is still not sufficient, please tell me, and I would try to record some desktop show.

Steps for reproducing:
1) start synaptic from gnome menu.
2) When main window is displayed (still disabled because synaptic is busy at start) point the mouse pointer to "Search" icon on window toolbar
3) Wait for synaptic main window become enabled
4) Try to click the search button (move pointer only inside button widget boundaries) - clicks do not work at all
5) Then move mouse pointer outside the button widget and back again
6) Click the button - now it works.
