One other Tip:
I am getting all okay if I restore default (couldn’t be other way)
I tried to put 5 lines of text “Small description for slide 1” in original slide nº1 and slide number 2 and I got the very same “black screen”
one question more
I’m dealing with pics up to about 100k and it seem to work fine, without “black, and no slide” background
Is it a SIZE issue from this template?
Thanks in advance
