I use Alt+Tab a lot and noticed after the December Windows Update that it is extremely slow to jump to a window using Alt+Tab. It is especially slow jumping to Windows Explorer. I tried a number of tests, but eventually shut down Display Fusion and everything returned to normal. Are there any known issues like this with Display Fusion or Windows? Do you have any recommendations to fix this? As it is now, I'm going to have to stop using Display Fusion because of the aggravation.
