I' using Boxcryptor personal unlimited together with Google Drive.
The options are set to crypt the filenames as well.
Everything works well as long as I use the local installation or the apps for the mobil devices.
But the Chrome Plugin goes into a permanent loop, if the number of entries for an folder does not fit to the page.
After trying to page, the plugin tries to de-crypt the filenames again and again, multiplying the entries in the file list of the browser.
The browser window is not usable any more and has to be closed.
Re-opening the window shows the content correctly until the first paging attempt is done.
As I have many folders containing more than a few files, this makes the whole plugin useless.
