Lags after lates OS X update!

Worked just fine and was very useful until latest OS X update!
Now every screenshot I make causes a beach ball.Besides every screenshot becomes visible couple of minutes after it has been made. Please fix app response time!
Something causes it to hang during all critical processes!

P.S. Will be back for an update and a better review after developers fix the bug.
