I had/have the same issues CruiseLite. I will say that after installing more RAM into my computer, the problem appears far less often. I am not suggesting that you spend more money on RAM, but more RAM is always good, especially under windows. I wonder (and may actually test) trying to allocate a specific amount of memory for the TD software and see if that helps... Right now, I am stuck in SnowZilla 2016, so I may get to it.
