6. Known Issues  Since we use NPAPI plugin for communicating with Chrome Browser and Win32 DLL, only the extension can be run in Microsoft Windows.  OS dependent problem  To solve this problem, we need to distribute this extension for each OS (mainly Mac OS, Linux) using other communication way, not Win32 DLL.  Linux : https://developer.mozilla.org/en/XEmbed_Extension_for_Mozilla_Pluginshttps://developer.mozilla.org/en/XEmbed_Extension_for_Mozilla_Plugins  Mac OS : http://niw.at/articles/2010/06/18/call-native-api-from-google-chrome- extension-on-mac-os-x/enhttp://niw.at/articles/2010/06/18/call-native-api-from-google-chrome- extension-on-mac-os-x/en  Calendar event can be updated only by Google Calendar webpage.  In Java, we can use Google Calendar API.  Problem with sharing session between Chrome browser and Java program is not solved yet. 6
