Is that the right mouse button click you are talking about? I assume it is. I haven't been here that long.
Been here since v1.03. I do know that I had some real problems with the deletions not working very well as it seemed to not really delete them and strange things would start to happen. So, through about V1.06, I created a level using the addon method. Creating a portion, then saving it and adding on to that and saving it under a new name. Like Level01a, Level01b and so on. I haven't done it that way in version 1.07 and 1.08. Seems to be working fine now. Just my observation.
