Paul,
in Notes Modul, in a note on the "Reference tab", clicking on the column headers has no effect. There is no sorting! Also the icon "Show linked notes" isn't working neither the other icons (the one with thunderbolt and no "Tool tip" and the "Open note" icon. I don't understand. Are these other bugs?
Thanks
Marcus
References sorting in note
References sorting in note editor will be added in 7.23 release. The icon you mentioned should be called "Show link references". Clicking on it should show all linked references of current record. This bug will be fixed in version 7.23. Thanks.
