IE7 and 8 are the most stable, Chrome, 360 Browser and Aoyou are all available. Sometimes there is only one line "***There are [1] PDF files, please click to browse. Public text [CN2012102623755000000201208010ACN0]" , but the bottom is blank and the details of the pdf are not expanded. Download and install "Adobe Reader X 10.1.0 Simplified Chinese Version" to solve the problem. Can this help you?
