Problem with custom "CTRL+

Hi,

I've got a problem with a custom shortcut both in Photoshop CS6 and CC. It works fine in Photoshop CS5.

I've set the "CTRL+<" shortcut to the "flatten image" command. I'm using it for years so this is hard to change my habits . I've saved the shortcuts and everything works fine until I restart Photoshop.

After a restart of Photoshop, the shortcut is automatically set to "CTRL+&" ! I've edited the ".kys" file where my custom shortcut is stored and the file is good :

I though may be it could be a problem with the custom workspace wich also store the shortcuts but this file is fine too.

I really do not know how this is possible as the files are correct... is Photoshop saving this values elsewhere ?

I'd really appreciate some help with this.

Thanks,

G.
