Just took a quick look at BattleSpriteAnimationEditor and I just got a bit of a surprise when I selected a frame record and noticed Bowie's sword was out of place : my initial click on the line deselected a checkbox even though I clicked outside of the checkbox, but in its table cell.
I may not have the same practices as others for selecting a table line, but I thought it safe to click on the widest void space :D
I don't know how easy that would be to ensure that only the checkbox itself should trigger a click event, and I don't want to make this a blocking issue of course so I'm only reporting in case there's an easy fix that makes sense to you.
