When a record is divided in more than a file in TS-Doctor, and when a "Stream Error Areas" box appears,
if an Error Area begins in other than the first file,
then a descriptor error pops up in the preview window, so no preview at all, and the following windows are incompletely drawed.
The only solution is to restart TS-Doctor.
Please look at the three jpeg screen captures in attachment.
Thanks for the feedback. I will check that.
