Strange problem with IVAP?

Hi to All:

I use PM A320,and i would to know if someone have a problem,when reached a
Flight level...the problem is:

-When the Aircraft reach the FL the V/S start to climb +300/400 fts and
descent -300/400 fts consecutivellly,all the flight!Once start he just stop this
process when we start our descent and reach FL between 240 and 270.

I fly all most the time online with IVAP(program interface from IVAO),and I
had conclud,for now,when I fly without IVAP,I don't have this problem...the
aircraft stay steady in the FL when reached.

This could be a problem between IVAP and PM?
Some incompatibility?

Thanks

Hi,

I tried to find a description of the way IVAP interacts with the autopilot
but I couldn't find that or download the software itself without an IVAO
account... can you point me to something? Does it have a selectable option
not to work with the autopilot or trim or something like that?

Ciao

Enrico
