windows 11 bug - regional settings with comma separated digital numbers hangs MoganSTEM-v2026.2.2

[sashadim]

in my pc, It doesn't recognize properly page size except for letter.
This is the "letter" page

This is A4 page

I think I've figured out the issue, which also occurred in version 2026.2.1, while 2026.2.0 worked correctly.
When the number format in Windows settings uses a comma for thousands and a period for decimals, the A3/A4/A5/B4/B5 page formats are correct in Mogan.
When the number format uses a comma for decimals and a period for thousands, the previous page formats are incorrect: in this case, Mogan attempts to format documents in infinitesimal page sizes and crashes.
To verify the problem, simply go to Windows settings, Language and Region, Regional Format: in English everything is fine; in Italian, the problem described with ISO series page formats occurs (after change of settings you have to restart Mogan).
