Welcome Navigators,
Reported in posts on the Forum - the various problems associated with the operation's skin - especially Arimi and Pongo.
Please remember that the development of the skin's and their refinement enforces some action from users:

Regardless of whether we are talking about skin Pongo, Arimi, O4i or Frontzosd (Thx for author's for their work and effort ) - should not be mixed between the skin's additions ux (unless the author explicitly permits it), and should always use appropriate and indicated for use with the skin - file data.zip

In another case, since there is a possibility of malfunction of the program.

PS. Read the exact - included descriptions - in them a lot of information what and where to apply !, or do not use.
