Korg ARP Odyssei

[maudan]

Hello everybody.
I recently bought the VST ARP Odyssei for Windows (version 1.3.0 as stated in menu).

The VST works but it's impossible to select the Arpegiator and the FX pages. Basically there are two buttons missing in the right high corner and in their place there are three buttons for enlarging or squeezing the window.
I opened a ticket to the support but with unsatisfactory results, since they say to scroll the page. Tried to scroll the page but without any result. Fact: the required buttons are missing.
Now I'm wondering about reduced performance set for Windows version.
If so this should be written on the site, and I haven't seen any of it.

Anyway I can control the FX using MIDI CC messages even though I don't have complete control of all parameters.

Has anyone else had this experience?
Thanks and regards
