I think this screenshot is self-explanatory.
Shouldn't I see all of the created slices when I export for the web? Instead, I just see one! Could it be that the file have a very high resolution (4k x 3k)?
Thanks in advance!
EDIT: I tried to save anyway and it works! It gives me all my slices in separate files. Why then I see only one in the export window? Not so much of an issue now, btw...
