LinuxQuestions.org - [SOLVED] Launcher's search function not working

Hi
I just installed Linux Deepin 2013 last week. Very impressived!

Ok.The Launcher work just fine previously, but after recently I've installed few tools/app like Oracle/sun jdk, Squirrel SQL, and Pinta, the Launcher's search seem not working right.
When Im using mouse hover to the top left or using keyboard (the windows icon there), it launch perfectly, but when I type something to search app the Launcher closed. I did few times, reboot the machine, but the issue still there. I cannot do search but have to find the app name and click it.
Thanks in advanced for any help.
