First of all thanks for the GOTO and File Manager Redesign! Much better now
Reporting a problem again (sorry to bother you so often)
I have a a scanned pdf which has four pages in one like this
1 2
3 4
But after reflowing the text is displayed in changed order 1 3 2 4. In other words - left side is displayed completely top-bottom and then the right side. Changing column numbers does not help at all. I hesitate to call it a "bug" as this is how you would normally expect Koreader to behave. But reporting nevertheless in case anybody has any ideas..
