Pixel dimensions in 3.7.3 on P-2-back

I started out 2005 with a Phase One P-2-back on a Contax 645 installing the supplied Capture One DB version 3.6 in Windows. The specifications for the P-2 back indicate a Pixels total: 4080x4080.

But, Meta Data (Ctrl+I) only showed me File>Image dimensions: 4080x4078 pixels and the processed image at 100% scaling and no cropping shows Width: 4076 and Height: 4080 pixels.

Recently I upgraded to Capture One vers 3.7.3 and the included Release Notes under \"Bug Fixes\" are telling me (second last row at the end): \"Width/Height in EXIF matches the processed image's size\".

Now in 3.7.3 Meta Data shows 4096x4094 pixels, but the Process Tab only has a Width/Height of 4076x4080, the same as before in vers 3.6 and what I get lateron in PhotoShop.

Was there no bug fixing yet, at least not in Windows???
I am still hoping for it.....
