"Split items at time selection (if exists), else at edit cursor" is splitting at the PLAY cursor instead of the EDIT cursor. For my uses I need it to actually split at the edit cursor.
I tested and this is also happening with "Split items at time selection, edit cursor, or mouse cursor." The action "split items at edit cursor w/ crossfade on left" appropriately makes a split at the edit cursor, however.
I'm on Windows 7 using the 64bit version of Reaper.
Thanks!
