I have to either
long click, press the trash can, and then in the dialog click trash

If I do a high lvl merge, there usually comes up one or two of those useless annoyances. That is the main reason I did not merge the Leek up to Chili peppers. That is about 4 mergers plus usually more than 4 of those pesky chests.
Ahhh. Merging shoots off healing too, but not much.And what I mean by 'heal by merge' is when you pull an item off of a square (doesn't have to be a dead square, but the same procedure applies) with a merge instead of spending pheromones to heal the underlying square.
