Nope, I'm saying that I've implemented something called
best shot selection, and that it sometimes fails to work, and I have no clue why.
I've put a few checks in the code that would give error messages in case weird things were detected, and the one I'm seeing most often is "File unreadable", which basically means that BSS thinks the latest shot was saved in file number N, but there is no such thing as file number N.
And that's about all I know about the problem. But since the BSS routine executes at exactly the same time as raw files are saved, and uses exactly the same functions to "harvest" filenames, the problems might be related.
See
this thread, it might very well be related.
