Hi volwrath
When I do that to a PDF file (turn on re-flow and change the text size), and go out of Mantano, then back into the file, the file shows in non-reflow view. But when I go into re-flow view, the increased text size has been "remembered". I am using Honeycomb 3.1 on a Lenovo Thinkpad for testing at the moment - latest paid version of Mantano. Hope that helps
Cheers,
M
