In v. 1.2 and 1.1.1 when choosing not to automount and mount read
only as the only settings in the options pane, after trying to mount
the ext2 partition I get an error message:
Message: Unknown Error
After that it is not possible for me to mount the partition any more.
The Info button will not change to the Option button neither. All
attemts with disktool didn't help.
