Yes, I tried annotations with ChoPro files. And as far as I can remember I didn't make changes to the files after completing the annotations. It is, however, possible that I accidentally changed one or more of the display options for ChoPro files. I'll try to explain why.
I have configured default settings for newly imported ChoPro files. But sometimes it seems that an imported file gets different settings. So I adjust the settings, "Set as Default", and "Apply to all other files" to make sure all files look the same. This may have changed something.
A feature I'm missing is the ability to change all display settings of a ChoPro file to Default. I though Reset would do that, but apparently it doesn't.
As soon as we have a more stable release I'll continue testing.
Thanks for the great job!
