Puggles
I have not found anyone else talking about this editing bug that I have and the program is being updated regularly, so am I the only one experiencing this?
In general, you can get around the clip editing bugs by using bounce-to-clips between edits.
Also, in your example you were moving the clip around a lot to get the right position. Before you try the second move, undo the first using CTRL+Z. When you're happy with it, bounce-to-clips.
The other thing I find helps, is to have the "create one clip per file" option checked in the save dialog.
Without this checked, Cakewalk/SONAR saves all its clip in the one file with internal references as to where each clip starts/stops. These internal references can get corrupted, although regular bounce-to-clips helps to refresh them.
I guess the idea behind having the one file was for performance reasons. This is less of a concern if you're using an SSD.
So in summary, use bounce-to-clips often - even if it's on each clip, bouncing to itself; and have the "create one clip per file" option checked.
