Thank you for getting back to me. I wonder if there is a misunderstanding of what I mean:
I am not referring to file naming. I mean the auto-population of the filter Suffix in the dropdown window on each event when a Filter has been selected. So, for example if in Event 1 I were to select Run, Light, Red… I would expect the next window “Suffix” to auto-populate “R”. It always used to but for some reason it is not doing so now and I wonder if I have inadvertently changed something that has stopped that.
Under the “Tools” tab, “Options”, “Sequence Options” there is a setting available to “Clear sequence suffix dropdown list” and I wonder if I have somehow cleared that. How do I put them back?
