I work with Firefox and Chrome on a MacBook pro... The same happens with RAMSAVE and RAMLOAD...
Well, I will try to start from scratch with another code and I will do some tests.. I will keep you updated if I find out something new.
Thanks!
Some clues...
It is possible save only in the first 2 locations... You can LOAD from any other location if the SAVE was made in the first 2 locations. If you SAVE in any other location, the slot appears full, but when you LOAD from that slot, nothing happens... Very strange... My code has got something bad. I will continue with the investigations...
