As I watch the loaded videos (I usually have 2-3 video tracks and 3 audio tracks) It stops being responsive. I have Vegas Pro 18, this happens usually as I am watching playback at 2X speed and attempt to click the timeline to move the "cursor." I twill freeze then when I click again the whole screen goes lt grey and it asks me to either close it or wait, I have waited for naught over an hour. Is there an error log somewhere I can access?
