Hi Dan,
thank you for the input. I think it might be related to Java version. I noticed yesterday when I got this issue that my Java 7 has installation date as yesterday but don't know how it was installed. I tried to download 7.40 but no access to download it. Requested my service desk for gui 7.40. Since my company only have 7.30 version for install right now. Not sure if I can get 7.40. I may try to downgrade Java to 6.
thanks,
Henry Li
