• If the GX/GP login function is changed while the Web application is in use, you may need to
reload the page or restart the browser. Follow the instructions in the message.
• If you are using the Web application with the Savethispasswordinyourpasswordlistcheck
box selected in the Java authentication screen that appears when you start the Web application
(this screen appears when you are using the communication login function) and change the
GX/GP Security settings > User settings, you must clear the Java temporary files on the
PC. If you do not, the old user registration information will be sent to the GX/GP, and the Web
application will not operate properly. You must also clear the Java temporary files if you save an
invalid user name or password.
ClearingJavaTemporaryFiles(forJava1.8(Version8))
From the Control Panel, choose Java > General tab > Temporary Internet Files > Settings >
Delete Files. Select the Trace and Log Files and Cached Applications and Applets check

• This application is signed with an electronic signature. When the application starts, it
automatically connects to the Internet and checks if the electronic signature has been revoked.

Control Panel > Java > Advanced tab > Perform certificate revocation checks on > Do not
check

EnhancedProtectionMode check box. Restart the PC, and then start the Web application.
• In some cases, immediately after you try to start the Web application, Internet Explorer displays
a message “A problem with this webpage caused Internet Explorer to close and reopen the
tab.” Then it reloads the webpage several times, and finally displays “We were unable to return
you to your webpage,” preventing the Web application from starting. If this happens, delete the
temporary Internet files of Internet Explorer, and try connecting again.
Click the tool button (gear icon), Internet Options, the General tab, and then Delete under
Browsing history. Select the Temporary Internet files and website files check box, and click
Delete. Then, close the Web browser, restart it, and then start the Web application.
• During operation, a message generated by the Web application or the GX/GP may appear. For

internal switch status displays require JRE. To use these functions, JRE must be installed in

We recommend that you use an environment in which only the compatible JRE version is installed.
If different versions of JRE are installed, JRE may not operate properly (such as when JRE 7 and
JRE 8 are installed simultaneously). Open Control Panel > Programs and Features, and check
that JRE versions other than the compatible version are not installed.
