I have all the products within Object Desktop and there are 2 software's that seem to have issues with Windows 11.  First is Fences 3, which shuts itself off with a windows saying it has been disabled because of Explorer.  Now this issue may be part of the next one, because the next one affects the windows explorer frames.  

Windows Blind (latest release) when using Luna with texture, it will skin everything and seem to work as expected.  Until you open of an explorer window and the top of the windows have been changed in Windows 11, which what I think the issue is.  The Explorer window will have a box over the top bar area and that seems to be where the issue is.  This will also cause an issue with explorer and things start to go south after that. If I unload Windows Blinds things work again after a reboot.
