I converted the .txt files to .prc problem gone
it appears to be a bug with .txt files only.
I had dragged the .txt files into main memory
to test wether it was neccesary to convert
every time. It would appear it makes sense
although as I said in my first post one .txt
file worked and 3 did not!
Thanks for your interest
I will try again with different files but time for bed
now want to read my books!!
