I like your software a lot and hope very soon you will succeed to remove all bugs.
This what I report is not a big problem but is irritating. Hope you will fix this in final release of PTP2.
I have all panos of same resolution and dpi but sometimes all tiles are equal, some times not and some of them are smaller. I don't know why because I tried also to open the same project few times without change anything and it is not always same. Every time it displays different. You can see one of those situations in my screenshot.
