NIS 2010 main window will open and minimize to task bar automatically

Every time I switch the video output of my laptop from one to another, e.g. LCD to VGA, or play a full screen game, NIS 2010 main window will open and minimize to task bar automatically.   I reinstall the product and find that this problem only happens in ver. 17.5.0.127. The previous version is OK.
