Normally to drag I
Now when I click on an item a popup shows up showing a window into the content of the file. So now I cannot move a file from one folder to another. Does anyone know the fix for this issue?
If I enable three-finger dragging then it takes away my ability to use three-fingers to slide between screens.
Sounds like you've got a Mac with a force-sensitive trackpad and you're pushing hard enough to trigger Quick Look. Don't push as hard to get a regular click; you can disable "Force Click and haptic feedback" in Trackpad System Preferences.
