Endpoint Protection 12.1 windows animation slowly after install
I just installed my first Version 12.1 unmanaged Symantec Endpoint Protection 64-bit on a Windows 7 64-bit system. After installing - all dialog boxes/windows opening, closing, minimizing or maximizing - animate VERY slowly, as if the system is moving in slow motion.
This is a test box. The software is my NFR version - I'm loading it on internal systems before I begin selling licenses of 12.1 to clients.The Windows system has the latest Windows Updates/SP1. Version installed is: 12.1.1101.401 (Release), RU1 MP1.
I have tried disabling Symantec Endpoint Protection - it makes no difference. If I uninstall the problem goes away. If I reinstall it comes back. I have tried this on a Dell Win7 box and on a Lenovo box. Same behavior. I have not changed any Win 7 Aero settings or any Performance Options/Visual Effects settings in Windows 7. Mainly as I don't feel I should have to change default Windows behavior to get Symantec software to function and not disrupt the end-user experience. The machine functions normally otherwise.
Does anyone have any thoughts what is wrong?
