The crashing occur when I try to manually add films and try to adjust the details, like language, media type or subtitle, etc. Mainly when I used one of them more than once and then after adding a different one and want to return the previous one after. (the top of the list from the rolling menu)
Could you please describe a simple procedure that will make the program crash, every time. Please describe what movie you select, what video, what field, etc... I'll reproduce the procedure on my computer, to see if it crashes for me too. If it doesn't crash on my computer, I'll create a test version to understand why it crashes on yours.
