I am pretty sure I have worked out that it is the length. It worked to find some stuff but wasn’t find everything in the string. in the search window there is the string and it changes colour for my view (I cant work out how to post a pic here so am using bold=blue italics=green)
fight_N|figure_N|firefighter_N
Thanks for your help, I am now just manually going threw all my strings and cutting them down. Pretty sure that it is only when they are too long that I had any problems opening files.
Cheers!
