Problems with Toucan Encryption using ccrypt

I have problems using the "encryption" feature which behaves like described in this topic https://portableapps.com/node/21358.

After starting the job ccrypt obviously never returns and terminating this process results in a return=1.
I've tested the encyrption with ccrypt separately and got the following result:

ccrypt -e -K pw test.txt
ccrypt: encrypt write-protected file test.txt (y or n)? y

The script is waiting for a confirmation and that obviously also happens when trigerred by Toucan. As the file is "not" write-protected, I guess the problem is caused by the combination of Windows XP (that's my OS) and "cygwin1.dll" which is used by ccrypt.

@Toucan developer(s):
It would be very nice if you could add a possibility to handle those confirmation questions or if you just always make toucan using the "force" option "-f" in the ccrypt commandline.

Thanks for your support
