First, I'm not a novice. I have been using TT for 20 years. I was an hour into doing my return and had multiple windows open. At one point I started closing some and accidently clicked on the upper right corner X of the TT window. The program immediately shut down losing an hours worth of data. There is no opportunity to save anything . The net: if you hit the X you lose everything since your last save. THIS IS A HUGE BUG that needs to be fixed.
