SUPPORT REQUESTED: a340-300 / WINWING MCDU Periodic Freezing

[Arty57]

Good day. I have been trying to sort this out ever since initial release (day 1).  Originally the WINWING MCDU did not work with the a340.  Now after five updates to the a340 and a similar amount to SimApp Pro (SAP) the MCDU works, but not consistently or reliably, at least for me.

I am on SAP 1.16.75.  I am on a340-300 1.0.5.  All WINWING hardware has firmware checked and is current.  The symptom of this failure is as follows.  Initialize plane at gate on APU.  Enable SAP.  MCDU and FCU/EFIS come alive and function. Set fuel and weights via EFB and Simbrief. Flight Plan into MCDU via SOP.  When everything is set depart as normal.  Every flight at some point the MCDU freezes.  Screens locked. LSKs and buttons still function as can be seen on virtual cockpit MCDU. Only the physical MCDU is affected and only then the screen.  This usually occurs within the first ten minutes of flight, sometimes sooner, sometimes later.  When this happens a power cycle of my switched and powered USB3 8 port hub restores functionality of the MCDU and it operates without issue until the next occurrence at which time a power cycle is needed again.  Rinse and repeat throughout the entirety of the flight, two, three even five hours.  I have never once experienced a flight without an MCDU freeze and most flights are two or more.

As I type this I am engaged on a test flight KLAS to KBOS.  In the first 30 minutes of this five hour flight I have had two MCDU freezes.  The MCDU is the only component in the WINWING chain that is affected.  The virtual cockpit MCDU and physical FCU and EFIS continue to work as expected and all functions of those components are available.  I have Airbuses from other vendors, Fenix and FSL, that operate the same way (MCDU, FCU/EFIS via SAP) that have dozens of flights each, never once with a lockup or freeze. Only the iniBuilds a340 exhibits this consistent anomalous behavior and failures.  A solution is desired and requested.  Please assist.
