When I double click on a Simplenote to edit it, if it is a different height to what is set in the current Style, the height automatically resest to that of the current Style and stays that way, even when I'm finished editing. However, if I single click on the Simplenote and edit it within the Properties dialogue box the text remains the same.

Is there a system variable that can be changed to prevent this from happening, or is it a glitch?
