Yikes, Sorry about the size of the image!
Following up on the above, I now cannot change the numbers of bars per line in the Layout section. I keep getting a red message in the bottom RH corner "Command is unexpectedly complex". This happens even if I try to reset the layout back to default (Def). Tried closing the file and restarting the program, even rebooting but still the same message.
I hope you can help.
Kind regards,
Iain
