I have been using BoxCryptor for a few months and I am having serious issues on my new laptop running Windows 7.
The easies symptom to describe is this: if you double-click on a data file residing on my BoxCryptor X: drive, the corresponding application fails to start (e.g. double click on a docx file, Word does not start). Similarly, if you create a shortcut on the desktop pointing to a file on the BoxCryptor drive and double-click it, an error is shown indicating the file cannot be found. The file, however, can be opened from within the application with File->Open.
It turns out that the BoxCryptor drive does not seem to implement Windows 7 security and "executing" a file in these conditions is not allowed.
Question: is the BoxCryptor drive NTFS or FAT32?
