I am using Indesign CC 2015.2. Randomly, my ability to drag anything is nonexistent, whether it be an image, text box, layer or paragraph style. I have looked this issue up before and have tried to follow the given fixes such as deleting the preferences and restarting the program, but it still doesn't work and it seems that beyond that there hasn't been anymore ideas. Whenever I restart the computer completely it works for varying amounts of time but always eventually stops allowing me to move anything which is frustrating. All other features seem to still be working. Any idea how to fix this?
