Yesterday, I actually ended up starting completely over on the entire document. The problem kept on reoccurring. I will try again, this evening, but it certainly isn't very user-friendly, whereas much of the program is. If, as you say, the program doesn't tell you that there's a problem, and if there's no way to reset an object which got scaled wrong, that strikes me as a rather poor design of that particular "feature.""
The core problem, for me, is that it is a deal breaker, on the purchasing end of things. If it does this, it's usefulness plummets dramatically. Of course, with any new product, there will be things that need to be smoothed out. The program certainly has a lot of very nice features. I have found the videos to be helpful. I appreciate being able to draw on the forum as a resource, also. I do, however, need to be able to consistently control the font size in documents created with Affinity Publisher.
