Wrong Parameter / Memory ID in App F1612

[SimoneMilesi]

Hello all!
For a single user i have a problem in the App F1612, Post Outgoing Payments: despite the user's defaults and parameters on company code (set to IT10), whenever she searches for a G/L account, they are filtered for another Company code (IT90)

Using the live search, we couldn't identify it, but opening the full search help the attached image is what we found.

What i tried to solve

1. First step has been clearing cache and cookies for the browser
2. Erase all the personal parameters and default from the user
3. Change PC to see if the behaviour changed.
4. Login via Gui and check / clear all the personal parameters.

Nothing of this worked so i'm scratching my head: how is it possible? If i use my user on her pc, the behaviour is correct, so i'm quite sure it's something related to the user, but i cannot find what.

Any hint?

Thanks!
