Boxcryptor drive mounted as X: files are accessible and sync works fine.
A folder with a lot of pictures (say 500), thumbnails get generated real-time on-the-fly which takes around 2-3 minutes. Go one folder up and then return to the pictures folder, and the thumbnails get re-generated again. It seems that Windows considers the X: drive as network / removable and it doesn't save the cache for thumbnails, even though Boxcryptor is set to Mount as fixed drive.
