i'm using a Hp pavilion dv6z laptop with Vista home premium 64bit. I'm trying to use Tune-up utilitie 2009, but i am unable to click on any button in tune-up's window. If i hover my mouse over an icon, it suppose to light up or change color because i'm selecting it but its not doing it( i have it installed on my other vista which is working fine). I can not even click the close button, i have to right click on taskbar just to cloes it. I am very certain the program did not crash, because it doing the system check up automatically. I can only open up tune-up's folder and use it program individually (tune-up is compose of alot of program such as defrag or system scan). Also i installed yahoo's widget (aka konfabulator), and i also experience the same problem. After i finished installing it, i am suppose to accept the license agreement but i can not click the scroll bar to scroll down the license agreement to click the accept button. I use both touchpad and have an mouse pluged in. I don't know whether its the mouse's problem or a problem in my system. I believe both program's interface is flash-based. Please help, thx.
