do not backup on time machine for windowsXP does not work

Hi,
although 'does not backup virtual machine works nice with Umbutu and Fedora with windowsXP I can set the 'tick in the box' but when I lock the configuration window it jumps back to 'not selected' I don't like this huge image to be loaded into my time machine backup.

Thanks!
Pete

 

what Mac OS do you have?

 

if you specify the Parallels folder in the Time Machine options, it will not be backupped.

 

I hope people in this thread have the same problem.
