XnView v1.74 Resize DPI Bug

Steps:
1. Load a 800x600 image (any image maybe) into XnView View mode
2. Choose Resize -> Standard Size -> 1600x1200
3. Change the DPI by going up by 1,2 or 3 (73,74 or 75dpi)
4. Change the DPI back to 72dpi
5. Screen Size now says "1599x1200" it should be "1600x1200"
I can re-produce this bug easily.
Sigh, another bug related to this...
Steps:
1. Load the same image -> mh.jpg
2. The Resize screen says 71dpi when it should be 72dpi
3. Go back and check image info and it says the image is 72dpi by default.
Some MAJOR calculation bugs here.

I can't reproduce it. You load a picture in 72 dpi, and in the resize dialog, you have 71 as DPI?

Yes, thats right.
It only occurs with "mh.jpg -

I just checked the picture with IrfanView,
DPI says 72dpi BUT the EXIF info says the DPI is 71dpi which is where the problem is!!!!

Ah now I understand, I didn't know that option existed.
Thank you for pointing it out.
