In Windows 8 while in the desktop, I will have programs get stuck in front. It has happened in multiple apps (Outlook 2013, Image Configuration Editor, Internet Explorer, (file)Explorer, Visual Studio). The window does not maintain focus, it just stays on top. Once it happens, it will never stop until the app shutdown and restarted. I can minimize the window and that works correctly.
It has been happening since I loaded Windows 8 Pro (clean install DELL workstation).
Now that I listed the apps that I use the most, I'm wondering if it's happened in non-MS apps. I'll have to pay attention.
