The animations are not working though the feature is checked on the performance option. It works if I uncheck and check again but only until I reboot the PC, after rebooting the animation disappear but the option is still cheked.
Not a fresh install. The last thing i installed before i noticed this problem was Microsoft Expression which also installed Microsoft Visual C++ 2005, 2008, 2010 Redistribution and Microsoft SQL server 2005.
It was the Citrix ICA Client causing windows minimise and maximise animation to stop working. Uninstalling the plugin fixes the issue but i still need the software for work.
Guess i have to contact citrix and find out a solution.
