#39 High CPU consumption when updating window title bar

[guma72]

I use RAAS together with putty. The problem arises when putty loses its connection to server, so it's not hard to reproduce it. I didn't deeply analysed the origin of this problem, but remarked that the icon on the title bar is flickering and when I unchecked the option of showing privileges icon on caption, the problem stopped. It seems that putty is changing its title bar and RAAS is constantly placing its icon. Maybe adding a delay of e.g. "windows tick" (55ms) is the best solution.
