I have a theory that it's always the first object in the block that acts up. I'm going to see if I can make something out that consistent.

The problems I had in the first part of this exercise, both in the Synthwave page and the Comic page, were the first objects in the block. They had Stretch To Fit Width components, and I blamed that...but now I'm thinking maybe not. The Magic & Violence, and T-Shirt pages both worked as you'd expect...and both had a simple block with one line of text. Nothing fancy, nothing edited. I had huge problems with the Home page, which also has manipulated content in the first block. I spent so much time learning what did what that I can't really remember what i did. I also didn't have access to the Blocks toolbar at the time.

I'll grab the Xara machine tomorrow and have a play.
