This bug has been discovered after the 1.1 final release.
Whenever a file is opened via a double click event in Windows Explorer, Caditor assumes the file has been modified before even touching it and gives a "Do you want to save your changes" dialog. The reason behind this has currently not been investigated but is expected to be patched with the 1.1.1 update.
NOTE: this bug applies to all versions of the 1.1 release. This includes 1.1.0-0 and 1.1.0-1. This bug should not be a security threat but is rather, a minor inconvience.
The patch should be out by tommorow.
