I have noticed while trying to use some old Poser Utilities such as RSR to PNG Converter they do not work in Windows 11! Also some problems when adding earlier Poser runtimes to Poser 11 and 12 some of the mat poses are a problem. Inked for instance will not work from a Poser Pro 2014 runtime in Windows 11! There are others. When Microsoft stops supporting Windows 10 in 2025 we may have further problems unless some of these programs and utilities are updated! Cheers
