Jiffi exit issue

Hi,

I have one small unsolved issue on Windows 8 x64, when I run JIFFI it does convert my files to the correct output file.

The output files do work, so the conversion is done, but the Jiffi program doesn't exit, and keeps running in memory. I need to END TASK in the windows task manager to stop Jiffi.

I there someone who has a solution ?
