On one computer, I have found the following issue. The timeline does not stop at the stop frame and not rewind to the beginning in the looping playback, it continues to increase frames at infinity. In this case, an attempt to stop playing causes Mobu to crash. In other words – to normal work with this failure is simply impossible.
The solution to this problem is as follows:
Find the file configuration tasks in Mobu
My Documents \ MB \
and in the group [Transport], group [Timing], specify the properties values for Processors equal to all.
This manipulation allows you to sync threads and fix timeline issue.
