Recently a user reported a bug of the Across Server mode in Windows. It is the mouse hotkey configuration doesn't work well and therefore the mouse hotkey is always enabled regardless of the mouse hotkey enable setting. The version 1.03a only patches this bug. So if you are using the mouse hotkey, you can skip this update. If you want to apply the update, you can't update with overwriting a previous version because the version of the installer is still 1.03. So please install the new version after the removal of the previous version. No need to reboot your computer and remove the previous settings during uninstalling. Once reinstallation done, reboot your computer. If you are experiencing any other issues, please don't hesitate to let us know. Thanks and Happy Holidays!
