Cannot resize window in windowed mode?

My Kodi (ver 17.1 running on Win 10) was working fine for a while, but a couple of days ago I cannot see the bar that is usually on top of the screen while in windowed mode that allows me to minimize or X out of Kodi. I also cannot resize the kodi window or move it from screen to screen. It seems that window mode is working as I can see the task bar at the bottom of the screen when I switch from full screen and vice versa. For all intents and purposes, it may as well be jammed in full screen mode and its driving me up the wall. Any ideas on what the problem could be?
