I am trying to edit a video. Everything is working just fine, but when I try to split any piece of the last clip that I have, everything resets to as if I first opened movie maker. I click the undo button and everything comes back, but no matter what this happens if I split the last clip. I've split this clip earlier with the first few seconds of it and it worked fine but now its all weird. How do I stop this so I can finish my video? For reference, I currently have a Toshiba Satellite L15W on Windows 10 if that helps.
