11.2.2 hangs on changing buffer size

[VRW]

Just for the record, here on my system PT11.2.2 hangs on changing the buffer size within a session.
Happening in both directions. Cursor starts spinning and doesn´t come back anymore.
Have to shut down PT completely. When I open PT+the session again however the buffer has changed
to the required size and I can go on working like there has nothing happened before, no problem further on...
until the next time changing the buffer. Then the same procedure is required to get Pro Tools to work again.
Actually did not happen with 11.2.1. here at least.

Cheers.
