This latest update was Jan. 8, 2026. I also installed the windows thumbnails about the same time. Open Brush left the OB folder in my documents folder and installed a new one on my desktop. when I opened OB, it behaved like a new install. It also installed a Blocks folder on my desktop, although I have not installed Open Blocks yet. So, I copy/pasted my usual OB folder from my documents folder to my desktop, and set the folder that OB made to Open Brush 1 (so it couldn't read it). Then opened OB in VR and it seems to work fine. but it stores new saves in the folder on my desktop and treats it as if it was in my documents folder. I have no idea why it only sees the OB folder on the desktop. I thought maybe the target was moved to the desktop for convenience on the update. By the way, the windows thumbnails is really great!
