Stage 24 is part of the xmloutput to file routine, specifically the part that deals with runtime. I updated this recently and may have inadvertantly caused the issue, i'll look into it.
In theory MC can have 3 seperate threads scraping movies at the same time (Main movie search, change or rescrape movie, and drag and drop), while much of the code is shared in the forms of functions and subs, each of these threads have their own control routine. Their are minor differences between them, rescrape for example does not need to worry about the movie ID.
There are obviously issues here, which unfortunately I am unable to duplicate, but I will take a close look to see if I can identify the problems.
